docs: Replace ancient swrast conformance docs with more current information.

I don't think Mesa 4.0 swrast conformance is relevant at this point, just
point people to the current Khronos list.  Also, add some more information
on submitting results.

Conformance Testing
===================
The SGI OpenGL conformance tests verify correct operation of OpenGL
implementations. I, Brian Paul, have been given a copy of the tests for
testing Mesa. The tests are not publicly available.
This file has the latest results of testing Mesa with the OpenGL 1.2
conformance tests. Testing with the preliminary OpenGL 1.3 tests has
also been done. Mesa passes all the 1.3 tests.
The tests were run using the software X11 device driver on 24-bpp and
16-bpp displays.
Mesa 4.0 and later pass all conformance tests at all path levels. Note
that this says nothing about the conformance of hardware drivers based
upon Mesa.

Mesa as a project does not get certified conformant by Khronos for the
APIs it implements. Rather, individual driver teams run the
conformance tests and submit their results on a set of hardware on a
particular operating system. The canonical list is at Khronos's list
of `conformant
products <https://www.khronos.org/conformance/adopters/conformant-products/>`_
and you can find some reports there by searching for "Mesa",
"Raspbian" and "RADV" for example.
Submitting conformance results to Khronos
-----------------------------------------
If your driver team is associated with an organization that is a
Khronos member and has submitted conformance for your API on another
software stack (likely you're a hardware company), it will probably be
easiest to submit your conformance through them.
If you are an individual developer or your organization hasn't
submitted results for the given API yet, X.Org is a member through
Software in the Public Interest, and they can help submit your
conformance results to get added to the list of conformant products.
You should probably coordinate with board@foundation.x.org for your
first submission.
