Mount Bazel repository_cache, Go mod cache and Go build cache as volumes

This leaves us with only git_repository rules not being cached,
the worst offender being the edk2 recursive submodule clone.

See: https://github.com/bazelbuild/bazel/issues/5116

gazelle's repo lookup (running `go list`) is also not cached, even if the
repositories themselves are.

We can eliminate most of the remaining rebuild time by mounting
the entire execroot, however, this is currently foiled by a podman bug
(Bazel needs to execute lots of binaries inside the root):

https://github.com/containers/libpod/issues/4318

Test Plan:
Ran `bazel build scripts:launch`, recreated container, ran it again.

Build times decreased significantly:

    INFO: Elapsed time: 279.951s, Critical Path: 119.05s
    INFO: 477 processes: 476 linux-sandbox, 1 local.
    INFO: Build completed successfully, 497 total actions
