[Clang][PGO][UserManual] Specify usage of -b flag (#139763)

llvm-profgen cannot accept the perf profiles collected without `-b` and
errors out with a message `"Invalid perf script input!"`.

This can also be validated from the code in function
`checkPerfScriptType()` in `tools/llvm-profgen/PerfReader.cpp.`
