[mono] Replace -disable-fp-elim with -frame-pointer=all (#58195)

`-disable-fp-elim` was removed in LLVM 8 in commit b7cef81fd36c85e52b115b9ed6d1fb92d63781d6.
Also see https://reviews.llvm.org/D56351.

The replacement option, `-frame-pointer`, is still present in LLVM 11.

Fixes https://github.com/dotnet/runtime/issues/58112.
