The following methods were implemented:
- String.prototype.matchAll based on ECMA-262 v11, 21.1.3.12
- RegExp.prototype[@@matchAll] based on ECMA-262 v11, 21.2.5.8
- RegExp String Iterator Object based on 21.2.7

- Declarative environment no longer need to lookup the created binding for setting it's value
- Unfold vm_decl_var and vm_set_var into vm_loop to reduce error checks
- Reduce code duplication in ecma_module_connect_imports
- Fix deleted binding setting in `ecma_op_set_mutable_binding` (fixes#4468)

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

After the introduction of the Proxy builtin object there was
a possibility to traverse the prototype chain with an invalid object.
The prototype was freed before it's data/properties were queried resulting
in accessing invalid information.
By forcing the allocator to always do a gc (`--mem-stres-test=on` build option)
it was possible to trigger the issue without complicated tests.
New internal method:
* `ecma_op_object_get_prototype_of` which always returns the prototype
of an object and the return value must be freed (if it is valid).
Updated prototype chain traversing in:
* `jerry_object_get_property_names`
* `ecma_builtin_object_prototype_lookup_getter_setter`
* `ecma_op_function_has_instance`
* `ecma_op_function_get_super_constructor`
* `ecma_op_object_is_prototype_of`
* `ecma_op_object_enumerate`
Removed method `ecma_proxy_object_prototype_to_cp`

In Proxy.[[Get]] if the target.[[GetOwnPropertyDescriptor]] fails the
trap result should be freed.

'this' is a restricted keyword in C++ so it's a good practice to avoid it's usage as an identifier.

When accessing an error's type there is no need to check the Proxy
prototype (as there is none).

When shifting a negative BigInt value if the
shift count is very "big" the result should be -1.
eg.:
```
(-2n >> (2n*32n)) === -1n
```
Note: the `-2n >> (2n*31n)` already returned `-1n` prior this change.

Proxy flags (IsCallable, IsConstructor) can't be stored on the
property list compressed pointer. As adding a Proxy to a WeakSet
would add a property to the Proxy object causing failures down the line.
The prototype internal "slot" can be used to store there flags as
it is not used in case of Proxies (as per standard).

- Rework symbols to have the same value across realms
- Support realms for native functions
- Support test262
- Use new.target realms for constructing intrinsics

- Type for realm objects is introduced (ecma_global_object_t)
- Realm reference is added to built-in objects and ECMAScript functions
- Resolving built-ins, global environments, and scopes require realm object
- Unnecessary global object accesses are removed from the code
Missing: external functions and static snapshot functions have no realm reference
