* Update containerd1.7; google.golang.org/protobuf

Update to containerd 1.7 and move to `google.golang.org/protobuf`
from `github.com/gogo/protobuf/gogoproto`.

These two changes are intertwined, since containerd 1.7 changes its
ttrpc task server definitions and protobuff generation (as well as some
other API changes).
Additionally, the task server gRPC code is imported from containerd
directly, rather than being generated here, and that code now explicitly
imports `google.golang.org/protobuf` instead of
`github.com/gogo/protobuf/gogoproto`.
Upgrading to `google.golang.org/protobuf` also requires updating
the `containerd/cgroups` dependency to v3
(`github.com/containerd/cgroups/v3/cgroup1/stats/`).

The new `protoc-gen-go-grpc` generators do not allow directives such as
`gogoproto.customname`, so the `go-fix-acronym` command is used to
update acronym customization (which is what containerd does).

Updated `Protobuild.toml` to specify new generators.

Added an `Update-Proto.ps1` script to re-generate protobuf files locally
and in GitHub CI.

Add `protobuild` and protobuff `grpc` and `ttrpc` generators to
`tools.go` so they are tracked and vendored, and can be trivially
installed via `go install`.

`.\scripts\Verify-GoModules.ps1` does not surface roots cause of
inconsisteny and does not match local mod tidy/vendor steps.

Replace with explicit commands, which also matches rest of `ci.yml`
