freedreno/ir3: Implement lowering passes for VS and GS

This introduces two new lowering passes. One to lower VS to explicit
outputs using STLW and one to lower GS to load input using LDLW and
implement the GS specific functionality.

freedreno/ir3: Add has_gs flag to shader key

Since the presence of GS changes how the VS operates we need to track
that in the shader key.

We don't really need to impose this condition, but we do need to cope
with the slightly more general case.

iris: finish aux import on get_param

A buffer and its aux are imported separately, if the aux import is
not completed yet when resource_get_param is called, merge the
separate aux a.k.a the 2nd image into the main image.

mesa: Handle pbuffers in desktop GL framebuffer attachment queries

Once again, we were handling back-to-front in the GLES3 case, but not
the desktop GL case.

Fixes GTF-GL46.gtf30.GL3Tests.framebuffer_srgb.framebuffer_srgb_default_encoding when run with --deqp-surface-type=pbuffer --deqp-gl-context-type=egl.

We were looking at ctx->DrawBuffer when asking about the read buffer,
which was good enough for CTS purposes, but definitely not right.

gallium/xlib: Fix xmesa drawable creation

The first time you call glXMakeCurrent, current != ctx. As a result we
would never look up whether the drawable already had an XMesaDrawable,
and would instead always create one. Then XMesaBufferList would have two
different buffers for the same XID, and you'd be reading and drawing to
different places, and that's not what you want at all.

Instead just always look up the drawable.
