[clang][cli] Remove marshalling from Opt{In,Out}FFlag

We can now express all marshalling semantics in `Opt{In,Out}FFlag` via `BoolFOption`.

This patch moves remaining `Opt{In,Out}FFlag` instances using marshalling to `BoolFOption` and removes marshalling capabilities from `Opt{In,Out}FFlag` entirely.

This simplifies the decisions developers have to make when creating new boolean options:
  * For simple cc1 flag pairs, use `Bool{,F,G}Option`.
  * For cc1 flag pairs that require complex marshalling logic, use `Opt{In,Out}FFlag` and implement marshalling manually.
