Merge together MultiplatformHighlighting and MultiplatformAnalysis tests

Basically, the former uses an old quickly-scrapped infrastructure,
which were not applicable for HMPP, so  the latter tests were written.

So, both check for one and the same thing (highlighting in MPP projects),
but MultiplatformAnalysisTest is more modern,
and has a lot of inconvenient stuff in MultiplatformHighlighting fixed
