imports: stop using go/packages for modules go/packages needs to call `go list` multiple times, which causes redundant work and slows down goimports. If we reimplement `go list` in memory, we can reuse state, saving time. `go list` also does work we don't really need, like adding stuff to go.mod, and skipping that saves more time. We start with `go list -m`, which does MVS and such. The remaining work is mostly mapping import paths and directories through the in-scope modules to make sure we're giving the right answers. Unfortunately this is quite subtle, and I don't know where all the traps are. I did my best. cmd/go already has tests for `go list`, of course, and packagestest is not well suited to tests of this complexity. So I ripped off the script tests in cmd/go that seemed relevant and made sure that our logic returns the right stuff in each case. I'm sure that there are more cases to cover, but this hit all the stuff I knew about and quite a bit I didn't. Since we may want to use the go/packages code path in the future, e.g. for Bazel, I left that in place. It won't be used unless the magic env var is set. Files in internal and imports/testdata/mod were copied verbatim from cmd/go.
