This patch fixes these issues and typos.

Replace usage of jerryx_print_byte, jerryx_print_string with jerryx_print_buffer.
As we now have JERRY_ZSTR_ARG, so we can take advantage of it
With this, the jerry_port_print_byte port api won't need any more
this reduced the port api surface

Notable changes:
- Updated and the port API interface, new functions have been added
and some have been changed. The port library is now cleaned up to
not have any dependency on jerry-core, as it should be. The port library
is now strictly a collection of functions that implement
embedding/platform specific behavior.
- The default port implementation has been split for windows and unix.
Implemented port functions have been categorized and reorganized,
and marked with attribute((weak)) for better reusability.
- External context allocation has been moved to the port API instead
of a core API callback. The iterface has also been extended with a
function to free the allocated context. When external context is
enabled, jerry_init now automatically calls the port implementation
to allocate the context and jerry_cleanup automatically calls the port
to free the context.
- jerry_port_log has been changed to no longer require formatting to
be implemented by the port. The reason beind this is that it was vague what
format specifiers were used by the engine, and in what manner. The port
function now takes a zero-terminated string, and should only implement
how the string should be logged.
- Logging and log message formatting is now handled by the core jerry library
where it can be implemented as necessary. Logging can be done through a new
core API function, which uses the port to output the final log message.
- Log level has been moved into jerry-core, and an API function has
been added to set the log level. It should be the library that
filters log messages based on the requested log level, instead of
logging everything and requiring the user to do so.
- Module resolving logic has been moved into jerry-core. There's no
reason to have it in the port library and requiring embedders to
duplicate the code. It also added an unnecessary dependency on
jerry-core to the port. Platform specific behavior is still used through
the port API, like resolving module specifiers, and reading source file
contents. If necessary, the resolving logic can still be overridden as
previously.
- The jerry-ext library has also been cleaned up, and many utility
functions have been added that previously were implemented in
jerry-main. This allows easier reusability for some common operations,
like printing unhandled exceptions or providing a repl console.
- Debugger interaction with logged/printed messages has been fixed, so
that it's no longer the port implementations responsibility to send
the output to the debugger, as the port should have no notion of what a
debugger is. The printing and logging functions will now pass the
result message to the debugger, if connected.
- Cleaned up TZA handling in the date port implementation, and simplified
the API function prototype.
- Moved property access helper functions that use ASCII strings as
keys from jerry-ext to the core API.

Related to #4186.
Some notable changes:
- The term 'Error' now strictly refers to native Error objects defined in
the ECMA standard, which are ordinary objects. All other uses of
'error' or 'error reference' where the term refers to a thrown value is
now called 'exception'.
- Simplified the naming scheme of many String API functions. These functions
will now also take an 'encoding' argument to specify the desired
encoding in which to operate.
- Removed the substring-copy-to-buffer functions. These functions
behaved awkwardly, as they use character index to specify the
start/end positions, and were mostly used incorrectly with byte
offsets instead. The functionality can still be replicated with
other functions if necessary.
- String-to-buffer functions will no longer fail if the buffer is not
sufficiently large, the string will instead be cropped.
- Fixed the usage of the '_sz' prefix in many API functions. The term
'sz' means zero-terminated string in hungarian notation, this was
used incorrectly in many cases.
- Renamed most of the public API functions to have shorter, more on-point
names, rather than the often too long descriptive names. Functions are now
also grouped by the type of value they operate on, where this makes
sense.

Instead of a fixed number of arguments, a call info structure is passed
to the handlers, which can be extended in the future without breaknig the
API. This structure holds new.target value, so its getter function is removed.

In the jerry-ext there is a native 'assert' handler implemented.
This change adds extra backtrace information if an 'assert' call fails.
To print out the backtrace the library should be built with `JERRY_LINE_INFO` enabled.

New methods
* jerryx_set_properties: Allows multiple property registration for via a single call
* jerryx_set_property_str: Allows property registration without the need to
create the property name JS value. The property name can be directly passed
as a `const char*` value and must be zero terminated.
* jerryx_get_property_str: Allows getting a property value on a given object.
The property name can be directly passed as a `const char*` value.
* jerryx_has_property_str: Allows checking if a property exists on a given object.

This PR is a general cleanup for garbage collection and memory
allocation code paths.
Changes:
* Removed an unnecesary local variable from 'ecma_gc_mark'.
* Refactored 'ecma_gc_run' to have an implicit list head during
iteration, which results in one less condition in the loops,
and changed the loops to use compressed pointers to reduce the
overall amount of compression/decompression.
* Renamed 'jmem_free_unused_memory_severity_t' to 'jmem_pressure_t',
and added additional values.
* Removed 'jmem_free_unused_memory_callback', instead
'ecma_free_unused_memory' is now called directly.
* Reworked 'ecma_free_unused_memory' to handle all code paths related
to 'jmem_pressure_t', and moved all relevant code paths into this
function. This simplifies the code paths in other places.
* Reworked 'jmem_heap_gc_and_alloc_block' to be more streamlined.
* Changed mem-stats to not report unused pool chunks as allocated
memory.
* Created an allocator internal API for allocating/freeing memory blocks
that are not reported as used memory in mem-stats.
* Removed iteration statistics for the jerry allocator from mem-stats,
as they don't provide any actually useful information.

In the previous approach `jerryx_port_handler_print_char` was implemented
in by the jerry-default-port. This implementation however required the
jerry-ext handler header file which created a requirement in the
jerry-default-port for the jerry-ext headers.

Allow developers to choose whether they want a hard or a soft
implementation behind `assert`, i.e., whether they want to kill
the whole engine in case of an assertion failure in the executed
script or just throw a JS error.

Markdown files in the docs/ directory can now be annotated to turn
fenced C code blocks into unit tests. The recognized syntax is:
[doctest]: # (name="test.c", test="run")
```c
// unit test code
```
The commit also fixes the issues revealed during the initial
annotation.

Added `handler` module to `jerry-ext` to contain implementation of
commonly used external function handlers: `assert`, `gc`, and
`print`.
Also adapted jerry-main to use jerry-ext/handler
