This allows the tbo code to properly detect if we are using a buffer
as a texture or not, instead of relying on GL_TEXTURE_BUFFER being used.
We also don't need to special case generate the tbo texture id until

Take into account the gallium uniform buffer indices when associating
host UBOs with gallium uniform buffers.
Previously the code disregarded the gallium uniform buffer indices,
leading, under specific circumstances, to the provision of incorrect
data to the shaders. The problem manifested typically when a context
contained active UBOs which were not accessed by a particular shader,
but ended up being used instead of the correct UBOs for that shader.
This occurred, for example, when running the dEQP-GLES3.functional.ubo.*
in batch mode, in which case left over UBOs from previous tests would
cause subsequent tests to fail.

Update the blit shader creation code to take the destination format
swizzle into account. This involves inverting the swizzle information
and using the inverted swizzle to reorder the texel components in the
shader. The new swizzle code also removes the need for having a special
case if the destination format uses emulated alpha.
This commit temporarily removes the VIRGL_FORMAT_R8G8B8X8_UNORM special
case. Improved support for it, and other similar "ignore alpha" cases,
is added back in an upcoming commit using appropriate swizzles.
At the moment we always recreate the shader in case we have a swizzle,
but a more efficient shader caching scheme could be devised to improve
this.
