codec: proto2 groups (SGROUP/EGROUP wire format)

Plugin: detect protoreflect.GroupKind, emit kind='group' in the
field descriptor and a SGROUP opening tag in inline codegen. The
group body bypasses the LEN-prefix path entirely — encoder emits
start-tag, body bytes, end-tag in three slots; decoder calls
pb.codec.decode_group(desc, buf, pos, field_id) which reads inner
tags until the matching EGROUP id.

Wire layer already understood SGROUP/EGROUP for skip_field; the new
decode_group reuses the per-tag dispatch from decode_message but
stops on EGROUP instead of end-of-buffer. Repeated groups bracket
each element with its own SGROUP/EGROUP pair.

Runtime parser now desugars `optional|required|repeated group Name
= id { body }` into (a) a nested message named Name and (b) a
synthetic field of kind=group whose lowercased name is `name` — so
source-parsed proto2 schemas behave the same as build-time codegen.

Text format renders groups under the submessage's capitalized name
(`SingleGroup { ... }`) rather than the lowercase field name,
matching mainline protoc's convention.

Adds a vendored, MessageSet-stripped test_messages_proto2.proto in
test/conformance/proto/ (header comment documents the patch).
10 new luatest cases (group_*) cover singular + repeated + text +
descriptor kind, across both codegen modes. 739 tests pass.

--- This proto includes every type of field in both singular and repeated
--- forms.
---
--- Also, crucially, all messages and enums in this file are eventually
--- submessages of this message.  So for example, a fuzz test of TestAllTypes
--- could trigger bugs that occur in any message type in this file.  We verify
--- this stays true in a unit test.
