Add llvmPackages_latest.clang and bintools to the macOS part of
default.nix for nix, because for some reason the `ar` utility is not
found in GitHub actions right now.
Disable LTO for the macOS action for now, this is a consequence of
recent cmake refactoring and needs to be fixed.

Change CI actions to a matrix with cmake options, for both release and
debug builds, with ENABLE_LINK=OFF and ENABLE_SDL=ON configurations, for
all 3 runners.
Also add both g++ and clang++ to the matrix for the Ubuntu runner to
test on clang.
Disable the macOS workflow for now because brew is failing to install
dependencies.
