protobuf: remove gogoproto

Remove gogoproto in favor of the standard protobuf compiler and use
vtproto to supplement the standard protobuf compiler.

This removes any nonstandard extensions that were part of gogoproto such
as the custom types.

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.
