[Test] (MG_Test): catch the unit tests up with three deliberate behaviour changes

Browse Source 
ctest -L unit had been failing 13 of its 418 cases, all of them tests left asserting
what the code did before a commit that changed it on purpose:

- "restore target GL version to 3.3" put the advertised target back after the
  experimental 4.6 run, but the two Voxy sanity tests still demanded 4.6. The
  extensions they really care about are all still advertised, so assert 3.3 and drop
  the now-meaningless AtExperimentalCTSVersion from their names.
- "support rectangle textures where the emulation is exact" made every desktop-only
  target supported - rectangle included, stored as a plain 2D - while the texture
  test still expected rectangle to be rejected.
- "keep declared modern GLSL versions strict" changed two things at once: a
  normalized legacy directive now carries a marker on its line, so the ten tests
  matching "#version 330 core\n" whole no longer match; and a version the
  application declared itself is no longer raised to 460, so the sources declaring
  330/400 keep their own number and only MobileGL's own normalization is retargeted.

Test expectations follow, rather than the implementation being bent back: each of
the three changes is the intended behaviour and is argued for where it was made. The
retry test now drives the 460 escalation from a legacy "#version 130" source, which
is the only thing that is still rescued, and gained a case pinning the other half of
that contract - an application-declared "#version 330" stays at 330.

418/418 unit tests pass.
