  Fix GenerateMipmap when base level or max level are set
  
  According to GLES 3.0.4 section 3.8.10, GenerateMipmap should generate
  levels based on the base level, and generate them at most up to the
  max level. Levels outside the base/max level range should be unchanged
  by GenerateMipmap.
  
  The Texture class is fixed so that the image descs are set only for
  the changed mipmap range when GenerateMipmap is called.
  
  The D3D backend is fixed so that mipmap generation is correctly
  started from the base level instead of level 0, and making sure that
  mipmaps are generated only up to the max level. Generating mipmaps for
  array textures is also fixed for cases where the base level depth >=
  max(width, height) * 2.
  
  The GL backend is fixed to sync texture state before GenerateMipmap is
  called, so that base level and max level are set correctly in the
  driver.
  
  The GenerateMipmap entry point is refactored so that it has a separate
  validation function and a context function which does the work.
  Validation for out-of-range base levels is added.
  
  New tests are added to verify the functionality. One corner case in
  the tests fails on NVIDIA GL drivers likely due to a driver bug -
  similar rules for GenerateMipmap are found from newer GLES specs and
  also OpenGL specs (checked versions 3.3 and 4.4).
