Remove ScriptTypes and ScriptExtraHeaders headers

The first header was used to include the SpiderMonkey JS API at once,

provides modular headers allowing us to include what we use, refs #8086.

Some defines have to be moved to compiler options but it is apparently
a mistake from the SM developers:
