Toolchain upgrades

[xddxd]

Switches to a Ubuntu 18.04 docker container for Linux builds. Now it uses GCC 10.3 and Clang 12 for compilation, CMake (minimum as well) and Ninja versions are also bumped. Also bumps the LLVM submodule to a later commit. Removes the xcb hack, bumps minimum compiler versions. Switches BSD to Clang 12.

edit: do not merge yet, waiting on hcorion to push a newer docker image.

[Nekotekina]

So it works now? Maybe bump minimal required compiler versions as well.

[xddxd]

Done. For documentation purposes: I tested the removal of the xcb hack and it worked fine on my manjaro system with an amd gpu.

[Nekotekina]

BSD build tries to fetch llvm-11, I guess if it can be fixed now we are good to go.

[hcorion]

We should also bump minimum CMake, but that can be done in a follow-up pr

[xddxd]

I have no idea what's up with BSD, @jbeich could you take a look?

[Nekotekina]

Well, clang 11 can be fine for now as minimal requirement. Switching to gcc-10 is more important.

[jbeich]

@xddxd, apply f6a2b29: libc++ 13 (snapshot) saves it into <__config_site> during build. In future bundled libc++ may need to be built instead of simply extracted.

Example <__config_site> from FreeBSD

Don't forget the BUILDING.md :)

[xddxd]

Should be good to go.

[Blitzwing1]

On Pop_OS 20.04 every build past this commit no longer start. 0.0.15-12166 works correctly.

rpcs3: error while loading shared libraries: libOpenGL.so.0: cannot open shared object file: No such file or directory.

[hcorion]

Can you open an issue for this @Blitzwing1 ? In the meantime, you can install libopengl to fix the issue
