{lib}[GCCcore/9.3.0] Mesa v20.0.2, zstd v1.4.4, lz4 v1.9.2

(created using eb --new-pr)

Main changes with the update of Mesa to v20.0.2:

• This PR follows the proposed changes for Mesa in change Mesa 19.1.7 + 19.2.1 easyconfigs to use custom easyblock for Mesa #9764 and Change options based on arch for Mesa easybuild-easyblocks#1892 , which automatically sets appropriate configopts for the system's architecture. The mesa easyblock seems very close to be ready. If it turns out that it is too much work to have it merged on time for 2020a, this easyconfig for Mesa can be switched back to generic mesonninja very easily.
• As a consequence of using per arch configopts, patch Mesa-19.2.1-meson-avoid-march.patch is no longer necessary.
• Comments in the header of the easyconfig updated reflecting all these changes
• Added new dependency on zstd
• Removed dependency on nettle, which is no longer required
• Depends on LLVM v9.0.1 ({compiler,tools}[GCCCore/9.3.0] LLVM v9.0.1, re2c v1.3 #10133). For the time being this seems the candidate to be merged into 2020a.
• sanity_check_paths has moved to the mesa easyblock:
  • Libraries in sanity_check_paths have been reduced to those that I think are not arch dependent (i.e. ignoring libs such as libswrAVX2.so). Let me know if those are not working on your system.
  • Headers in sanity_check_paths have also changed quite a lot because many of them are no longer installed in builds based on libglvnd (check include/meson.build in the build directory).

Output of glxinfo | grep OpenGL in my test system is as good as it was with Mesa v19 and glxgears shows similar performance
