Add optional support for streaming FLAC and OGG/vorbis audio.
Galaxy style from OpenMusic is over 40 MiB in wav. FLAC gets it down to about 27 MiB and OGG/vorbis can get it down to just 1.36 MiB. I think vorbis should be our primary format for distributing OpenRCT2 assets due to its low size, but FLAC is available for those who want higher quality assets.
This supersedes #16095
The position and size arguments of WindowCreate are now optional - not a window doesn't have to know the size beforehand.
This removes the WF_NO_SCROLLING flag from the call to WindowCreate, but that seems to have no use for the scenery window anyway.

Introduce more transparency toggles and allow each one to be set to either an invisible or ghost state which is a persisted user setting.
A new window is introduced to control these settings and is inspired by OpenTTD.
- Changes all references of `VIEWPORT_FLAG_INVISIBLE_PEEPS` to `VIEWPORT_FLAG_INVISIBLE_GUESTS` and `VIEWPORT_FLAG_INVISIBLE_STAFF`
- Updates Invisible People menu item and shortcut.
- Added new viewport flags into the `viewport_set_visibility` function
- Invisible options only work if see-through is activated as well
- Added see-through supports
- Regression: Exclude ride from invisible no longer works (ride is still see-through)
`enabled_widgets` was used to enable input for widgets. However I do not recall anywhere this being used to specifically disable a widget which doesn't use the dedicated `disabled_widgets` flag. I don't think there is any purpose in keeping this, so I have removed all uses of it.
