[llvm] [FunctionAttrs] Remove unused legacy-PM runImpl template (NFC) (PR #202983)

[Aditya Medhane via llvm-commits]

https://github.com/flash1729 created https://github.com/llvm/llvm-project/pull/202983

`runImpl` here is a leftover from the legacy pass manager (it takes `CallGraphSCC`), with no callers since the legacy PM was removed. It never instantiates, so it trips `-Wunused-template`. Removing the dead template.

NFC.

Part of #202945.
