Add a new instrumentation section type `[sample-coldcov]` to support`-fprofile-list` for sample pgo based cold function coverage. Note that the current cold function coverage is based on sampling PGO pipeline, which is incompatible with the existing [llvm] option(see [PGOOptions](https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/Support/PGOOptions.h#L27-L43)), so we can't reuse the IR-PGO(-fprofile-instrument=llvm) flag.
