SI-9540 typedFunction is erasure aware

When typer is running during erasure, must assign erased FunctionType
in typedFunction. This removes a bunch of unneeded casts now we no longer
assign a half-erased FunctionType.

I poked around a bit, and it looks like erasure doesn't want typer
to erase built-in types (like Unit/Any/Nothing).
They are already treated specially during erasure.
