This patch deduplicates the contents of reusable-tsan.yml and reusable-ubsan.yml, making them one. The new workflow replaces the duplicated ones in the top-level build.yml and are called with different sanitizer parameters.

It is based on Hugo's patch. Context:

@hugovk I think this needs backport labels to keep the CI in other branches close.

@hugovk hugovk added needs backport to 3.13 bugs and security fixes needs backport to 3.14 bugs and security fixes labels Jul 20, 2025

Sorry, @webknjaz and @hugovk, I could not cleanly backport this to 3.13 due to a conflict.
Please backport using cherry_picker on command line.

Hmm, we didn't have UBSan in the 3.14 branch yet. I'm fine with having it there (and 3.13), but also to revert #136883 if it's not necessary to backport.

@encukou Should we have this just in main, or also backport?

but also to revert #136883 if it's not necessary to backport.

I'd suggest reverting partially if needed, but the job grouping and generalization are good to keep.

@hugovk ultimately up to you, but, if it works on 3.14 I think we should keep it working.
Not on 3.13 though -- we'd need to backport #111178 to make UBSan pass.
