There are several main changes in this PR:
Create envoy.api.v2.core packages to break circular dependencies from xDS on to subpackages on to base protos.
Create individual packages for each filter and add independent versioning to each filter.
Add visibility constraints to prevent formation of dependency cycles.
Add gogoproto annotations to improve go code generation.
After moving xDS service definitions and top-level resource protos back to envoy.core.api.v2, cycles were created, since the second-level definitions depend on base protobuf definitions, and are in turn included from xDS; however xDS and base definitions are in the same package.
The solution is to split the base protos into another package, envoy.api.v2.core. That eliminates dependency cycles (validated using go-control-plane).
Added a few gogoproto annotations to improve golang code generation.

* Added PGV C++ generation support. This (hopefully temporarily)
abandons using native proto_library in favor of pgv_cc_proto_library.
We maintain build support for proto_library for the glorious future in
which we write a Bazel aspect to run PGV against the native
proto_library shadow graph.
* Replace min_len with min_bytes on strings, until PGV gets not-empty or
min_len support for C++.
* Various fixups for places where the PGV plugin objected to
annotations.
