protobuf: add vtproto as a supplemental marshaler

vtproto is an extra protobuf compiler that generates special methods
suffixed with `VT` that create typed and unrolled marshal and unmarshal
functions similar to gogo that can be used for performance sensitive
code. These extensions are optional for code to use but buildkit uses
them.

A codec is also included to utilize vtproto for grpc code. If the
package `github.com/moby/buildkit/util/encoding/proto` is imported then
vtproto will be used if it exists and otherwise it will use the standard
marshaling and unmarshaling methods.
