internal/testenv: add NeedsGo helper

Some tests and packages need the go command.
For example, go.dev/cl/499255 adds a package that uses `go mod
download` and some of its tests won't work if the test environment
doesn't have 'go' (e.g. android, ios, wasi/wasm builders).
NeedsGo skips the calling tests if 'go' isn't available.
x/tools and go projects have similar facilities already, but
this is simpler than golang.org/x/tools/internal/testenv's NeedsTool
or Go project's src/internal/testenv's MustHaveGoBuild.
We just check whether `go env GOROOT` returns something convincing.
