game: fix Classic/TBC SMSG_TEXT_EMOTE field order

Browse source 
Classic 1.12 and TBC 2.4.3 send SMSG_TEXT_EMOTE with the field order:
  textEmoteId(u32) + emoteNum(u32) + senderGuid(u64) + nameLen(u32) + name

WotLK 3.3.5a swapped senderGuid to the front:
  senderGuid(u64) + textEmoteId(u32) + emoteNum(u32) + nameLen(u32) + name

The previous TextEmoteParser always used the WotLK order, causing senderGuid
to be read as a mashup of textEmoteId+emoteNum for Classic/TBC. Emote
animations and chat entries were associated with wrong GUIDs.

TextEmoteParser::parse now takes a legacyFormat parameter; handleTextEmote
passes it based on expansion detection.
