Fully support @@species and SpeciesConstructor in Array and Promise builtins.
Also added partial support to TypedArrays, but a rework is needed in %TypedArray%.prototype functions' typedarray constructor, which is out of this patch's scope.

The patch also revealed a minor issue about Map[Symbol.iterator] which have been fixed as well.

There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.
Main changes:
* Renamed all CONFIG_DISABLE_<name>_BUILTIN macro to JERRY_BUILTIN_<name> format.
* The special JERRY_BUILTINS macro specifies the basic config for all es5.1 builtins.
* Renamed all CONFIG_DISABLE_ES2015_<name> to JERRY_ES2015_<name> format.
* The special JERRY_ES2015 macro specifies the basic config for all es2015 builtins.
* Renamed UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
* All options (in this change) can have a value of 0 or 1.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
JERRY_REGEXP_STRICT_MODE is set to 0 by default.
* Reworked CONFIG_ECMA_NUMBER_TYPE macro to JERRY_NUMBER_TYPE_FLOAT64 name and now
it uses the value 1 for 64 bit floating point numbers and 0 for 32 bit floating point
number.
By default the 64-bit floating point number mode is enabled.
* All new JERRY_ defines can be used wit the `#if ENABLED (JERRY_...)` construct to
test if the feature is enabled or not.
* Added/replaced a few config.h includes to correctly propagate the macro values.
* Added sanity checks for each macro to avoid incorrectly set values.
* Updated profile documentation.
* The CMake feature names are not updated at this point.

Currently, `lit-magic-strings.inc.h` is manually maintained. This
has several drawbacks:
- keeping the list of magic strings sorted first by length then
alphabetically is error prone,
- it is easy to leave unused magic strings in the list by accident
(e.g., `LIT_MAGIC_STRING_JERRY_UL` is defined as a magic string
but not used anywhere in the code) and,
- it is very hard to add `CONFIG_DISABLE_*_BUILTIN` guards to the
list, even though there are several magic strings, which are used
in some of the configurations only (e.g, "setPrototypeOf" is used
in ES2015 only).
To ease the maintenance of magic strings, this commit moves the
definition of magic strings to a config file
(`lit-magic-strings.ini`), and adds `tools/gen-magic-strings.py` to
generate the `.inc.h` file from this config file and from the use
cases of the strings in the code.
- The magic strings in the config file can appear in any order, the
generator will ensure that they are correctly sorted.
- The generator skips those definitions that are not used anywhere
(and emits a warning to signal that such definitions can be
removed).
- The generator applies the same guards to the definitions in the
`.inc.h` file as found in the code around the use of the strings
to optimize for size.
The commit also changes some builtin-related `.inc.h` files by
adding guards that don't affect functionality but improve the
results of the generator.
To ensure that the invocation of the generator does not get
forgotten, the commit also adds `tools/check-magic-strings.sh` and
binds it into the testing infrastructure.

The default definitions and undefinitions of macros used for built-in
descriptions (SIMPLE_VALUE, NUMBER_VALUE, STRING_VALUE, OBJECT_VALUE,
ROUTINE, ACCESSOR_READ_WRITE, ACCESSOR_READ_ONLY) are heavily cloned
all over the builtin-objects directory. This commit factors them out
into two header files, which are then included in the place of the
clones. This way, maintenance becomes a lot easier: e.g., if a new
macro gets introduced, default definition and undefinition don't have
to be added to all description files (of which there are 56 right now,
and their number will most probably just grow).

Since the project is now hosted at the JS Foundation we can move to unified copyright notices for the project.
Starting with this commit all future contributions to the project should only carry the following copyright notice (except for third-party code which requires copyright information to be preserved):
"Copyright JS Foundation and other contributors, http://js.foundation" (without the quotes)
This avoids cluttering the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly. Also dropping the year from the copyright notices helps to avoid yearly code changes just to update the copyright notices.
Note that each contributor still retains full copyright ownership of his/her contributions and the respective authorship is tracked very accurately via Git.
