Add a new command to list formulae that aren't bottled for a given OS.

- `brew uninstall --zap` replaces `brew cask zap`
- clarify how `--json` should behave

Fixes https://github.com/Homebrew/brew/issues/9296

This behaviour is disabled.

Do the usual deprecate/disable dance for the Homebrew 2.6.0 release.

Not to be merged until the next release will definitely be 2.6.0.

and allow to skip missing workflows

Can be used like this:
brew pr-pull --workflows=tests.yml,wheezy_tests.yml --ignore-missing-artifacts=wheezy_tests.yml PRNUMBER

- Suppress (some more) warnings when doing `brew install --quiet`
- Clarify `man brew` output that we don't suppress all warnings
  for all commands with `--quiet`

While I was doing this I noticed references to the (soon to be
deprecated) `brew switch` so:
- remove these references in `install` output
- remove a reference in the documentation
- add a comment to remind me to deprecate `brew diy`, too

Fixes #9179

Fix `-1` and other flags so they're handled correctly with casks. Use
the "right" exceptions for declaring invalid combinations and change
their parent class so that `--help` is printed nicely too.

Fixes #9033
