Convert scripts in developer/bin to Homebrew commands

[bevanjkay]

This is a proposal for how deal with the scripts in developer/bin.
Below is what I think we can keep / remove.

Migrate to a Homebrew Command

• casks-without-zap
• find-appcast
• generate_cask_token
• list_recent_pkg_ids (potentially combine with list_pkg_ids_by_regexp command with arguments)
• list_pkg_ids_by_regexp
• list_loaded_launchjob_ids (potentially combine with list_installed_launchjob_ids command with arguments)
• list_installed_launchjob_ids
• list_running_app_ids
• list_id_in_kext
• list_ids_in_app
• list_ids_in_pkg (potentially combine into list-in-pkg with arguments)
• list_payload_in_pkg (potentially combine into list-in-pkg with arguments)
• list_apps_in_pkg (potentially combine into list-in-pkg with arguments)
• list_loaded_kext_ids
• list_login_items_for_app

Potentially Remove

• list_url_attributes_on_file
• update_cask_family
• update_multilangual_casks
• cask-pr-local-check
• cask-pr-inspect-download

Requires Python for Protobuf handling so may be complicated to convert to Ruby

• import_google_fonts

Re-add font_casker script from homebrew-cask-fonts

• https://github.com/Homebrew/homebrew-cask-fonts/blob/88357e6c0516bf53524696393f12d4d073139a5d/developer/bin/font_casker

@Homebrew/cask
Interested in some feedback here to see what is used often.

I am not sure how many of the helpers we need to keep for building casks, as it seems most "ids" and "loaded items" are discovered on CI anyway, which I personally don't have a problem with.

@Bo98 advised that we can probably use https://github.com/mrkn/pycall.rb for the fonts one.

Is the proposal to move them to $(brew --repo homebrew/cask)/cmd (like homebrew-core's rebottle command)? If so: makes sense.

Some of the more generic ones that would be useful for third-party cask taps could be in Homebrew/brew, with modifications. For example, integrating scripts like generate_cask_token into brew create (and/or an audit) probably makes sense.

Yeah, this exactly.
