[InstrPGO] Avoid using global variable to fix potential data race (#114364)
In https://github.com/llvm/llvm-project/pull/109837, it sets a global
variable(`PGOInstrumentColdFunctionOnly`) in PassBuilderPipelines.cpp
which introduced a data race detected by TSan. To fix this, I decouple
the flag setting, the flags are now set
separately(`instrument-cold-function-only-path` is required to be used
with `--pgo-instrument-cold-function-only`).
