Exclude known thirdparty/ ubsan errors

[hpvb]

In my quest to make ubsan failures a build failure I've added all current ubsan errors by type to a new suppression file which we will then also use with CI.

The idea is to only add known ubsan errors to this file, so this is not a blanket exclusion of thirdparty/ this means that if we get new or unexpected ubsan in thirdparty/ builds would fail.

Thanks!

Is this the reason why github actions fails to run the test project in master?

UndefinedBehaviorSanitizer: failed to read suppressions file '/home/runner/work/godot/godot/bin/misc/error_suppressions/ubsan.txt'

I don't think those are failures, the test projects still run fine I believe.
But yes the suppressions don't seem to work, there's a mismatch between the relative path used and how it's resolved from the binary itself.

This seems to fix it in linux_builds.yml.

  TSAN_OPTIONS: suppressions=${{ github.workspace }}/misc/error_suppressions/tsan.txt
  UBSAN_OPTIONS: suppressions=${{ github.workspace }}/misc/error_suppressions/ubsan.txt
