Robert Griesemer 952df98158 cmd/compile: accept constraint literals with elided interfaces
This change enables the relaxed syntax for constraint literals
as proposed in issue #48424 and adds a simple smoke test for
the compiler. (Most of the relevant changes are in the syntax
and types2 package which have more extensive tests for this.)

This makes it possible to experiment with the new syntax while
we contemplate the fate of #48424.

If #48424 is accepted, this change can remain. If #48424 is
not accepted, reverting this CL will remove this feature in
the compiler.

For #48424.
