Introduce new dynamic dottype operations which take a dynamic

b27c7e30dc [dev.typeparams] cmd/compile: fix HasShape, add dottype test
HasShape needs a TINTER case.

Add a test for x.(T) in various situations. Needs the fix above.

Also remove ONEW unshapify case. It is ok for ONEW to have a shape
type, as it will just be passed to mallocgc, or possibly used as a
stack object type, both of which are ok.
