[debugserver] Fix logic to extract app bundle from file path

Fix the logic to find the app bundle in a path by correctly accounting
for paths containing multiple occurrences of `.app`. The new logic will
correctly extract `com.app.Foo.app` from `com.app.Foo.app/com.app.Foo`.

[mlir][nfc] Fix typo in documentation comment

[clang][cli] Add MarshallingInfoEnum multiclass

This patch introduces a tablegen multiclass called `MarshallingInfoEnum`. It has the same semantics as `MarshallingInfoString` had in combination with `AutoNormalizeEnum`, but it's easier to use and follows the convention used for other `MarshallingInfoXxx` multiclasses.

[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.
