1. [CMake][Release] Disable PGO (llvm#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.
   
   (cherry picked from commit 0d2bb7f)
