[llvm-driver] Remove llvm-profdata from the driver (#162191)

llvm-profdata uses cl tool for command line parsing which declares
global options which clash in a multicall driver build. As a result
operations such as `llvm-profdata --help` prints options which are
unrelated to llvm-profdata when built in multicall mode.
