Frontend: Introduce -experimental-lazy-typecheck action.

Browse Source 
This action is currently just an alias of the `-resolve-imports` action.
However, it's named to more clearly reflect the purpose which is to do the
minimal typechecking needed in order to emit the requested outputs. This mode
is intended to improve performance when emitting `.swiftinterface` and `.tbd`
files.
