Remove JERRY_CONTEXT_INVALID_NEW_TARGET (#3643)
Until now JERRY_CONTEXT_INVALID_NEW_TARGET was used to represent whether the eval called from the script directly.
This information can be retrieved from the parser, so it simplifies the runtime handling of the new.target.

This patch fixes #3630, fixes #3640 and fixes #3641.

Rework the core of class parsing/runtime semantic (#3598)
Changes:
 - Use the pre-scanner to provide information for the parser about the existence of the class constructor
 - The allocation of the super declarative environment is no longer needed
 - The VM frame context holds the information about the this binding status
 - Reduce the number of class related VM/CBC instructions
 - Improve ecma_op_function_{construct, call} to properly set new.target

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.
