In case of a TypedArray the input `byteOffset` argument must be a
multiple of the `BYTES_PER_ELEMENT` value.

The property descriptors must be free'd during the iteration in the
Object.assign even if the property is not enumerable (or there is no value/getter).
Fixes: #4048

I've removed the ecma_op_object_get_property_names method, and implemented the following ones:
- ecma_op_object_own_property_keys: this is now the internal [[OwnPropertyKeys]] method
- ecma_op_object_enumerate: this is used for the for-in iterator
- ecma_object_sort_property_names: this is used for sorting the property names of an object
- ecma_object_list_lazy_property_names: this is for getting the lazy instantiated properties
- ecma_object_prop_name_is_duplicated: this is for checking if a given property is duplicated in an object
Also the for-in operation with Proxy object works with this patch, #3992 should be closed

Removed an undeterministic subtest.
date-construct.js fails intermittently, because it expects that
two Date() calls return the same date string. But the second one
can be 1 second later. This subtest is undeterministic and already
covered by test262/es2015/test/built-ins/Date/S15.9.2.1_A2.js with
1 second epsilon.

Now the following conventions are applied:
- passing the number of arguments for a function call is always uint32_t
- string size/length/position related operation should use lit_utf8_size_t
- Extended objects internal fields must be uint32_t

The algorithm is based on ECMA-262 v11, 19.4.3.2
Also added a custom dispatcher for the Symbol prototype

The toJSON method should be searched on the `this` object
only once. In case of normal objects there were no problems
however when a Proxy object is used as the `this` argument
for the Date.prototype.toJSON method the Proxy's `get` method
was invoked twice.

Removed the enumerable option when listing properties to prevent an extra
[[GetOwnProperty]] function call for Proxy objects.
In this case all the property names are collected, but the Object.assign()
implementation has already taken care of the enumerable property filtering.

From ES 6 the ToPropertyKey operation is used to convert elements to a valid property key.
This "new" method uses the ToPrimitive operation which can call the `@@ToPrimitive`
well-known symbol to convert the given element to a key.

This patch updates the early return types in the parser to SyntaxError instead of ReferenceError
in ESNEXT
This patch also includes a lot of tests for LeftHandSideExpression validation when using the = operator

We can apply this change to methods which use older standards, because
of the backward compatibility the result is the same
