This moves most misc/cgo tests to cmd/cgo/internal. This is mostly a trivial rename and updating dist/test.go for the new paths, plus excluding these packages from regular dist test registration. A few tests were sensitive to what path they ran in, so we update those. This will let these tests access facilities in internal/testenv. For #37486.
