GLContext: Don't map compatibility profiles to core profile if the latter are not available (restrict profile aliasing) ; GLProfile does this - Simplification.

GLContext shall not map compatibility profiles to core profile if the latter is are not available (restrict profile aliasing).

If a user requests a straight GL3 core profile, don't answer with a compatibility profile, e.g. GL4bc.

Hence this patch exposes the true GL profile situation more honestly the the user!

User can already query profile mappings via GLProfile, i.e.
  - GL2GL3,
  - GL4ES3, or via
  - getMaximum
  - getMaxFixedFunc
  - getMaxProgrammable
  - getMaxProgrammableCore

This also fixes an issue when a user requests 'getMaxProgrammableCore'
but would receive a GL4bc profile.
