CubeMap fixes

The following changes are done in this cl:
- Added multilayer support in Blitter::blit()
- Fixed Image::texelOffsetBytesInStorage() for cubes, since there's
  a 1 pixel border around it, so pixel offset (0,0,0) should be an
  extra line (1 pixel offset in Y) + 1 pixel (1 pixel offset in X)
  from the beginning of the buffer
- Added a number of out of bounds memory access asserts, which
  helped debug this issue.

Fixed failures in:
dEQP-VK.api.copy_and_blit.core.blit_image.all_formats.generate_mipmaps.*
Note: The only failures left in that category are related to filtering
sRGB images, which most likely happens in the wrong colorspace.

Tests: dEQP-VK.api.copy_and_blit.core.blit_image.all_formats.generate_mipmaps.*
