[CMake][Release] Disable PGO (#88465)
Running the test-release.sh script with PGO enabled causes build errors
like:
ld.lld: error: Function Import: link error: linking module flags
'ProfileSummary': IDs have conflicting values
I believe this a build system bug due to the PGO profile data being
generated unconditionally. If you run `ninja check-all` and then `ninja
install` like we do in test-release.sh, then the profile data is
regenerated during `ninja install` and some of the clang tools which are
not test dependencies get build during the ninja install step with
different profile data. When these tools link against the LLVM
libraries, like libSupport, we end up with these errors.
