virtual/wine: update for arm64+wow64, drop IUSE="proton staging"

Detailed changes:

- proton,staging: never quite liked these IUSE, this virtual is
  not intended for users to pick wine through USE (they can just
  e.g. add wine-staging to world file), and seems no packages
  depend on specific wine variants through this and it would be
  annoying for users to set these USE if they did

- wow64: allowing as an option should remove the need for users
  to unset abi_x86_32 when they use it

- keyword for ~arm64, it's an option now and no need for keywordreq
  for a virtual

- drop REQUIRED_USE, arm64 is also an option over abi_x86_* and
  there's no real reason to enforce at least one being set here

- while here, swap `abi_x86_64=` by `abi_x86_64?`, the former
  tend to give confusing portage messages and is not needed here
