Fixes macos-11 tests (#1197)

For some reason, brew suddenly stopped working on macos-11 GHA instances. The only place we were using brew was to install sccache, so these changes remove the use of brew to install sccache and instead install sccache manually. These changes also run all tests on macos-11 instead of selective tests.
