Adds bcdec lib to convert compressed DDS textures to RGBA based on what the system supports. BC7 if BPTC extension not supported, DXT? if S3TC extension not supported. Should support cubemaps and volume textures but those were not tested. Addtional changes: - remove indexed DDS support since it had bugs but didn't work anyway (R8 should be used instead) - fix issues with volume textures (nothing to test with) - remove old compression support flags as they are now obsolete Fixes #4920
