Assign shortcuts by default to only the quick access items (#4622)

# Description of Changes
Change shortcuts to just be a limited set for Quick Access tools rather
than for everything to avoid breaking browser key commands by default.

Also fixes a bunch of types of variables that were representing
`ToolId`s (I stopped at `automate` because there's loads in there so
I've just introduced some `any` casts for now 😭)
