Sync flags from `CMakeLists.txt` to `util/util.bzl`.

This currently uses only flags from the non-`MSVC` case, and adds the
following flags:

- `-Wnon-virtual-dtor`
- `-Wtype-limits`
- `-Wvla`

NOT including; with bazel this one generally has to be set in the root
project of whatever wants to embed BoringSSL:

- `-fvisibility=hidden`

Also, sorted the flags in each `CMakeLists.txt` definition
alphabetically to allow easier comparison between the two.
