Add new type which represents pointer with tag value (#3591)
jmem_cpointer_tag_t is newly added to represent pointer along with tag value.
This new type is first applied to scope_cp to mark initailized function properties (length, name) later

Fix lexical scoping between scripts (#3558)
This change fixes the handling of lexical blocks when executing multiple
scripts, and also fixes a few issues with module environments.

After this change, all script files will run in the same context and
will have access to lexically scoped global variables of previous
scripts, and module environments will no longer have a bound global
'this' value.

The REPL implementation in main-unix is also fixed to correctly handle
lexically scoped variables.

Fixes #3561.

For every bytecode in the above function, i created a new VM_OC group code

is a faster runtime.

Notable changes:
* Extracted the pure JS/builtin and external C method invocations
  into two new methods (`ecma_op_function_call_{simple, external}`).
* Updated parser/scanner to handle "new.target" correctly.
* Added JS test case.
