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.
