[llvm] [NFC]Rename collectPGOFuncNameStrings to collectGlobalVariableNameStrings (PR #70287)

[Mingming Liu via llvm-commits]

https://github.com/minglotus-6 created https://github.com/llvm/llvm-project/pull/70287

- `collectPGOFuncNameStrings` is reused a lot in [pr/66825](https://github.com/llvm/llvm-project/pull/66825) to collect vtable names. This function currently just takes a list of strings as input so name it to `collectGlobalVariableNameStrings`
- Do the rename in a standalone patch since the method is used in non-llvm codebase. It's easier to rollback this NFC in case rename in that codebase takes longer.

Subject: [PATCH] [NFC]Rename collectPGOFuncNameStrings to
 collectGlobalVariableNameStrings
