cmd/go: split out cmd/go/internal/base
This is one CL in a long sequence of changes to break up the go command from one package into a plausible group of packages. This sequence is concerned only with moving code, not changing or cleaning up code. There will still be more cleanup after this sequence. The entire sequence will be submitted together: it is not a goal for the tree to build at every step. For #18653.
