[libc] suppress more clang-cl warnings (#117718)
- migrate more `-O3` to `${libc_opt_high_flag}` - workaround a issue with `LLP64` in test. The overflow testing is guarded by a constexpr but the literal overflow itself will still trigger warnings. Notice that for math smoke test, for some reasons, the `${libc_opt_high_flag}` will be passed into `lld-link` which confuses the linker so there are still some warnings leftover there. I can investigate more when I have time.
