Integrates vtproto into buildx. The generated files dockerfile has been
modified to copy the buildkit equivalent file to ensure files are laid
out in the appropriate way for imports.
An import has also been included to change the grpc codec to the version
in buildkit that supports vtproto. This will allow buildx to utilize the
speed and memory improvements from that.
Also updates the gc control options for prune.

Removes gogo/protobuf from buildx and updates to a version of
moby/buildkit where gogo is removed.
This also changes how the proto files are generated. This is because
newer versions of protobuf are more strict about name conflicts. If two
files have the same name (even if they are relative paths) and are used
in different protoc commands, they'll conflict in the registry.
Since protobuf file generation doesn't work very well with
`paths=source_relative`, this removes the `go:generate` expression and
just relies on the dockerfile to perform the generation.
