[flang][driver] Add `-fdebug-dump-parsing-log` This patch adds `-fdebug-dump-parsing-log` in the new driver. This option is semantically identical to `-fdebug-instrumented-parse` in `f18` (the former is added as an alias in `f18`). As dumping the parsing log makes only sense for instrumented parses, we set Fortran::parser::Options::instrumentedParse to `True` when `-fdebug-dump-parsing-log` is used. This is consistent with `f18`. To facilitate tweaking the configuration of the frontend based on the action being requested, `setUpFrontendBasedOnAction` is introduced in CompilerInvocation.cpp. Differential Revision: https://reviews.llvm.org/D97457
