Fix csi-snapshotter RBAC yaml version

Update patch release notes generation command

The approach taken here extends the existing support for
cross-compiling binaries on the build host and specifying the Go
compiler: Go is installed if needed (as in Prow testing), binaries are
build on the host, then one image is created for each platform, and
finally those are combined into a single multi-architecture image.

cloud build: initial set of shared files

"make push-multiarch" matched both push-multiarch and push-%.  This
seems to be none-deterministic and in at least one
repo (external-provisioner), make picked the wildcard rule which then
failed because there is no "multiarch" command.

This ambiguity gets resolved by instantiating the wildcard rules only
for existing commands. The advantage also is that "make
push-no-such-command" will fail with an obvious "No rule to make
target 'push-no-such-command'" instead of attempting to build the
command.

It's not a real file and thus should better be marked as phony.

Most repos inherit the default BUILD_PLATFORMS, which includes
Windows, but don't have the necessary Dockerfile.Windows yet. To
simplify the rollout of multiarch image builds, Windows binary
building continues to be tested (i.e. BUILD_PLATFORMS remains
unchanged), but push-multiarch skips Windows if the Dockerfile.Windows
is missing.

multiarch windows fix

If the Dockerfile needs to run some command, that step fails unless
QEMU is set up properly first:
      failed to solve: rpc error: code = Unknown desc = failed to load
      LLB: runtime execution on platform linux/ppc64le not supported

cloud build: initialize support for running commands in Dockerfile

As discussed in kubernetes/k8s.io#943, we want
to consolidate under k8s-staging-sig-storage.
