Rework module parsing and execution (#4462)

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.
