SCons: Remove redundant `-fomit-frame-pointer` and `-ftree-vectorize`

- `-fomit-frame-pointer` is included automatically by both GCC and
  Clang in `-O1` and above.
- `-ftree-vectorize` is included automatically by GCC in `-O2` and
  beyond, and seems always enabled by Clang.

Closes #66296. See that issue for a detailed investigation.
