  [NFC][LLDB] Make it possible to detect if the compiler used in tests supports -fbounds-safety (#169112)

This patch makes it possible to detect in LLDB shell and API tests if
`-fbounds-safety` is supported by the compiler used for testing. The
motivation behind this is to allow upstreaming
https://github.com/swiftlang/llvm-project/pull/11835 but with the tests
disabled in upstream because the full implementation of -fbounds-safety
isn't available in Clang yet.

For shell tests when -fbounds-safety is available the
`clang-bounds-safety` feature is available which means tests can be
annotated with `# REQUIRES: clang-bounds-safety`.

API tests that need -fbounds-safety support in the compiler can use the
new `@skipUnlessBoundsSafety` decorator.
