cli/parser: Don't treat args with --cask as formulae

Browse Source 
- For the command `brew install --cask racket`, a user was reporting the
  behaviour where despite `--cask` in the command, they were getting
  output about the `racket` formula having been renamed:

```
$ brew install --cask racket
Warning: Use minimal-racket instead of deprecated racket
==> Downloading https://mirror.racket-lang.org/installers/8.7/racket-8.7-x86_64-macosx-cs.
==> Installing Cask racket
[...]
racket was successfully installed!
```

- The "instead of deprecated ..." messaging comes from the `TapLoader`
  class `formula_name_path` method, so _something_ must be assuming
  that everything is initially a formula before _later_ learning from
  further args parsing that there's a `--cask` qualifier to scope to
  only casks.

- There are always `@formula_options` and args parsing is recursive,
  going through each option, so we check that the original `argv` items
  include a `--cask` and skip calling the `formulae` method if that's
  the case.

- After this change, the "formula renames" words no longer show up.

```
$ brew install --cask racket
==> Downloading https://mirror.racket-lang.org/installers/8.7/racket-8.7-aarch64-macosx-cs.dmg
==> Installing Cask racket
[...]
racket was successfully installed!
```
