GitHub Action: add iOS build

This is incredibly brute force, downloading a 3+GB installer and
installing all of the Qt/iOS binaries.

This first attempt is mainly to get an idea how long this will take and
if this will fit within the size constraints of the build VM.  This
commit doesn't even try to build, yet.
