Subject: [PATCH] feat: fire CHAT_MSG_* events for all incoming chat messages

The SMSG_MESSAGECHAT handler stored messages in chatHistory and
triggered chat bubbles, but never fired Lua addon events. Chat frame
addons (Prat, Chatter, WIM) and the default ChatFrame all register for
CHAT_MSG_SAY, CHAT_MSG_WHISPER, CHAT_MSG_PARTY, CHAT_MSG_GUILD, etc.
to display incoming messages.

Now fires CHAT_MSG_{type} for every incoming message with the full WoW
event signature: message, senderName, language, channelName, displayName,
specialFlags, zoneChannelID, channelIndex, channelBaseName, unused,
lineID, and senderGUID. Covers all chat types: SAY, YELL, WHISPER,
PARTY, RAID, GUILD, OFFICER, CHANNEL, EMOTE, SYSTEM, MONSTER_SAY, etc.
