During the execution of the TypedArray filter method it is possible
to have a different sized output TypedArray than the input one.
When copying the data to the output array the values must be
correctly converted to the output TypedArray's value range.
Fixes: #4793

In the Array.slice method when the engine uses fast arrays the "end" value
was not updated if the input array's length changed. This can occur when the start/end
index normalization executes a method and the length is changed forcefully.
This leads to a buffer-overflow as the element copy reads too much data from the input
array.

In some parts of Proxy internal methods the compiler can do a bit of
tail call optimalization which would be ok, but the current stack limit
check framework in Jerry uses the stack pointer to calculate the stack depth.
This way of stack depth calculation is affected by the tail call optimalization
(as the stack does not increase).
By disabling the tail call optimalization at given points the stack limit calculation
will work as expected. This causes a bit of stack overhead, but the Proxy in it self
is a fairly big chunk of code and this stack limit would only be relevant if the Proxy
already does recusion which already very edge case.
The stack limit (--stack-limit=..) should be enabled to correctly report such stack
depth errors.

- Properties of namespace objects are ordered in lexical order
- The namespace object is created and imports are bound during linking phase
- Namespace imports are changed to read-only
- Reduced memory consumption

Only export the result of the assignment expression. This value cannot be changed later.

This patch disables automatic detection of module code, and instead
requires the user to explicitly specify whether to parse a source
as a module or as a script.
To achieve this the jerry_parse API function now takes a new option
which signals that the source should be parsed as a module.

Currently, ecma_op_get_prototype_from_constructor may return NULL
and the function didn't raise that exception.
Also optimize multiple assignment of prototype_obj_p and
multiple access of JERRY_CONTEXT (current_new_target) out.
This fixes https://github.com/jerryscript-project/jerryscript/issues/4463
