Implementation (but not plumbing) of the gRPC remote downloader

Extracted from https://github.com/bazelbuild/bazel/pull/10622

Per discussion on that PR, there's still some unanswered questions about how exactly we plumb the new `Downloader` type into `RemoteModule`. And per https://github.com/bazelbuild/bazel/issues/10742#issuecomment-595633454, it is unlikely that even heroic effort from me will get the full end-to-end functionality into v3.0.

Given this, to simplify the review, I'm taking some of the bits the reviewer is happy with and moving them to a separate PR. After merger, `GrpcRemoteDownloader` and its tests will exist in the source tree, but will not yet be available as CLI options.

Closes #10914.
