(ruby) Support encoding/decoding textproto format

[HoneyryderChuck]

What language does this apply to?

ruby

Describe the problem you are trying to solve.

Want to use a conformance suite from google described in textproto format, but the protobuf ruby build seems not to be able to understand the format.

Describe the solution you'd like

msg = Message.decode_text(bytes)
Message.encode_text(msg)

Additional context

python protobuf supports it via the text_format module. go supports it via Unmarshal. I don't know about the state of other builds.

The upb library which underlies Ruby Protobuf currently supports serializing to, but not parsing from, TextFormat: https://github.com/protocolbuffers/protobuf/tree/main/upb/text

So adding a text format encoder would be pretty straightforward. But adding a parser would require first adding upb support for that.
