  [clang][cmake] Apply bolt optimizations as part of the clang target (#119896)

This change removes the need to call the clang-bolt target in order to
apply bolt optimizations to clang. Now running `ninja clang` will build
a clang with bolt optimizations, and `ninja check-clang` and `ninja
install-clang` will test and install bolt optimized clang too.

The clang-bolt target has been kept for compatibilty reasons, but it is
now just an alias to the clang target.

Also, this new design for applying the bolt optimizations to clang will
be easier to generalize and use to optimize other binaries/libraries in
the project.
