Revert "Reapply "Add source file name for template instantiations in -ftime-trace"" (#99731)
Reverts #99545 There were a couple of issues reported in the PR: a sanitizer warning (https://lab.llvm.org/buildbot/#/builders/164/builds/1246/steps/14/logs/stdio) and a tmp file accidentally included in the commit.
