all: move //go:debug decoratemappings=0 test to cmd/go

test/decoratemappingszero.go is intended to test that
//go:debug decoratemappings=0 disables annonations.

Unfortunately, //go:debug processing is handled by cmd/go, but
cmd/internal/testdir (which runs tests from test/) generally invokes the
compiler directly, thus it does not set default GODEBUGs.

Move this test to the cmd/go script tests, alongside the similar test
for language version.

Fixes #72772.
