reflect/protoreflect: add FieldDescriptor.TextName

Add a new TextName accessor that returns the field name that should
be used for the text format. It is usually just the field name, except:
1) it uses the inlined message name for groups,
2) uses the full name surrounded by brackets for extensions, and
3) strips the "message_set_extension" for well-formed extensions
to the proto1 MessageSet.

We make similar adjustments to the JSONName accessor so that it applies
similar semantics for extensions.

The two changes simplifies all logic that wants the humanly readable
name for a field.
