Rework gopackagedriver to use driver protocol from x/tools

[sluongng]

There is now an official documentation for the Package driver protocol via x/tools https://pkg.go.dev/golang.org/x/tools/go/packages#hdr-The_driver_protocol

This is what gopls will be built upon, and we should consider migrating there to have better compatibility with gopls in the future.

Worth noting that our package driver could now be used to power tools other than gopls. This includes golangci-lint or other linters in the same category. In the future, we should also aim to support official Go tools such as govulncheck via a proper package driver.

I've made this change in our internal fork of gopackagesdriver. Currently waiting on approval to open-source it and contribute it back :)

I've recently found another case where this in theory would be handy, some go code generation tools like wire when in module mode use the package driver to resolve packages. But if they are used in a build step then they cannot call the package driver because the package driver is bazel itself which is locked (bazel server).
So far I managed to fall back on go path.

If anyone has another way of doing this or insight that would be interesting :)
Sorry for hijacking this.

Try using a different output_base, e.g. #3533

Thanks for the tip!
I considered this but found it to "feel off". Sorry for being unscientific about it.
I'll check out the issue you linked. Thanks again!
