gpu,gpu/shaders: [compute] decode sRGB texels in shader when EXT_sRGB is missing

Browse Source

This change avoids the hard dependency on GPU support for sRGB encoded
textures in the compute renderer.

With this change and the previously added CPU fallback, Gio no longer
rely on any GPU functionality outside the OpenGL ES 2.0 level.
