gpui-macros: Hide autogenerated action types/functions (#10417)

Piotr Osiewicz created 2 years ago

I've found it a bit annoying that autogenerated code shows up in
completions when working on Zed, so I've moved them into an associated
function of a struct we're "implementing" Action on. That way, neither a
generated function nor a static show up in completions.

Note that this change only affects Zed codebase! I'm pushing it up right
after last Preview to give it some time on Nightly.
