This patch adds bazel tests for llvm-libc.
Some math tests rely on the `mpfr` library. This is controlled via the `--@llvm-project//libc:libc_math_mpfr` flag. It can take three values:
- `external` (default) will build `mpfr` and `gmp` from source.
- `system` will use the system installed `mpfr` library.
- `disable` will skip tests relying on `mpfr`.
