[BACKEND] Set LLVM_ABI_BREAKING_CHECKS to be able to update the llvm version (#4512)

This PR is setting LLVM_ABI_BREAKING_CHECKS=FORCE_OFF, similar of how we
do it inside Google. In this way, we are forcing the structures that
relies in Hashing.h to use a deterministic seed.

We were not able to update the llvm version. The culprit llvm commit is
llvm/llvm-project@ce80c80,
that basically uses a non-deterministic seed if the previous "Flag" is
set.

There were some discussions in
#4338, and the other option
would be to check/replace code and tests that are overly depending on
the determinism of llvm/include/llvm/ADT/Hashing.h (DenseMap and
DenseSet mostly).

I think that the priority is first to be able to update the llvm
version, but if OpenAI is interested I could work on replacing them (for
MapVector), in order to fix all the failing unit tests, and then we can
set the LLVM_ABI_BREAKING_CHECKS again to "WITH_ASSERTS".

- [x] I am not making a trivial change, such as fixing a typo in a
comment.
- [x] I have written a PR description following these
  [rules](https://cbea.ms/git-commit/#why-not-how).
- [x] I have run `pre-commit run --from-ref origin/main --to-ref HEAD`.
- [x] This PR does not need a test because it's just setting a variable
for LLVM.
- [x] I have not added any `lit` tests.
