This CL changes fixedbugs/issue30862.go into a "runindir" test so that
it can use '-goexperiment fieldtrack' and test that //go:nointerface
works with cmd/compile. In particular, this revealed that -G=3 and
unified IR did not handle it correctly.
This CL also fixes unified IR's support for //go:nointerface and adds
a test that checks that //go:nointerface, promoted methods, and
generics all interact as expected.
Updates #47045.
