What does this PR do? Why is it needed?
I had an issue where the go packages driver was not loading all of the dependencies in a test resulting in unresolved imports. I tracked it down to the process of recompiling for internal/external in go_test. For the internal archive it is filtering out the dependencies that need to be recompiled, and recompiling them, but the final internal_archive does not include the recompiled dependencies. Later when the packages driver aspect lists the dependencies for the go_test target it is missing the dependencies which were recompiled.

Sorry to take a while to review. It's been a chaotic week. This code is also probably the most complicated logic in rules_go, so it takes a while to read back and understand.

1. Could you please ensure the tests cover this and reproduce the problem? Maybe add something to gopackagesdriver_test.go. That file creates a test workspace, then has test cases that run gopackagesdriver within that workspace in a few different ways.

2. For the actual code in test.bzl, I don't like that internal_archive is defined more than once, especially in a loop. internal_archive is also used a few lines below, and it's hard to reason about whether that happens before or after.

   Can this be fixed by changing some input to the go.archive call on L672? I think attr["deps"] is what eventually ends up as internal_archive.direct. So maybe internal_deps should include the recompiled version if available or the original version of each dependency? Currently it only includes the original versions.
