chore(libs): sync Ace3 to coa-ace3 (WoWUIDev master @ 52e5f2c)

Bring every embedded Ace3 / CallbackHandler / LibStub copy in line with the
canonical Exiles/coa-ace3 bundle so LibStub resolution is predictable across
all Exiles forks regardless of which addons are enabled.

Per-library MINOR moves:
  AceAddon-3.0          5 → 13
  AceEvent-3.0          3 → 4
  AceTimer-3.0          5 → 17  (C_Timer-based; available on the CoA client)
  AceHook-3.0           5 → 9
  AceDB-3.0            21 → 33
  AceDBOptions-3.0     12 → 15
  AceConfig-3.0         2 → 3
  AceConfigRegistry-3.0 12 → 22
  AceConfigCmd-3.0     12 → 14
  AceConfigDialog-3.0  49 → 92
  AceGUI-3.0           33 → 41
  AceLocale-3.0         2 → 6
  AceBucket-3.0         3 → 4
  CallbackHandler-1.0   5 → 8
  AceConsole-3.0, LibStub: unchanged (already at target)
