Associate versions to features in BrushFamily proto.

Add descriptors to associate ink.proto.Version values with messages, fields, and enum types in BrushFamily proto. This will be used in a future CL to write consistency tests to ensure all features have a minimum compatible version associated with them. `transitive_descriptor_set` and `options_cc_proto` will be used in a future CL.

Version `1.0.0` (stable 1) is being used to represent all the features that were available when Ink `1.0.0` was released (TODO: I think I have this right here, but where can I find the last commit on the C++ side that was included to confirm this?). Everything else is being lumped under the (presumed) next release of Ink, Version `1.1.0-alpha01` (if features get cut or pushed off, we can change them). We don't necessarily need this split, as there is no release of Ink which has versioning set with a maximum allowed version of `1.0.0`, so the actual `1.0.0` release will not reject brushes from `1.1.0-alpha01`. But, this distinction in the code now has been useful for testing purposes.
