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

+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.

+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.
