formats are involved.

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.

Ignores alpha channel while blitting R8G8B8X8_UNIFORM colorspace.
framebuffer It would be nice to perform some code refactoring in
vrend_blitter to minimize dup code. Fixes following test:
dEQP-GLES3.functional.fbo.blit.conversion.rgb8_to_rgba8']
dEQP-GLES3.functional.fbo.blit.conversion.rgb8_to_rgb10_a2
dEQP-GLES3.functional.fbo.blit.conversion.rgb8_to_rgba4']
