feat: value renderer for google.protobuf.Any (cosmos#13671)

* chore: skeleton files for any renderer

* feat: first cut at Any renderer and tests

* test: Any fields, more tests, rename lookup by field

* docs: make Any example match the stated spec, and the implementation.

* refactor: use protojson for better test case legibility

* test: use protocmp for proto equality

See https://developers.google.com/protocol-buffers/docs/reference/go/faq#deepequal

* refactor: use json.RawMessage instead of remarshalling

* refactor: consistent pointer receiver for Textual
