Try use self hosted linux runner to build html and latexpdf to check for errors.
Trying to use the build artifact didn't seem to work, so just run it on its own.
Upload docs/build folder as artifact to enable review without having to build
locally. Note: doesn't include verific, so will differ slightly from final
published docs.
pre_job will never skip something that is not skipped by pre_docs_job, so we can gate the build step by pre_docs_job to skip it when the two later jobs are both being skipped.
Remove compiler and cpp_std from `build-yosys` matrix. Using `config-$CC` will instead fall back to default values.
Drop `Tool versions` step and introduce `yosys-config` output instead.
Rename `test-builds` to `test-compile`.
`os_name` in include section needs to be explicit (putting it at the end doesn't
apply to the extra jobs).
Move macOS test to extra job instead of doing all gcc/clang (which isn't setup
for mac anyway).
Also adds name to build-yosys task.
