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.

Libraries updated in this fork:
  AceAddon-3.0           13  (5 → 13)
  AceComm-3.0            14  (6 → 14)
  AceConfig-3.0          3  (2 → 3)
  AceConfigCmd-3.0       14  (12 → 14)
  AceConfigDialog-3.0    92  (49 → 92)
  AceConfigRegistry-3.0  22  (12 → 22)
  AceConsole-3.0         7
  AceDB-3.0              33  (21 → 33)
  AceDBOptions-3.0       15  (12 → 15)
  AceEvent-3.0           4  (3 → 4)
  AceGUI-3.0             41  (33 → 41)
  AceHook-3.0            9  (5 → 9)
  AceLocale-3.0          6  (2 → 6)
  AceTimer-3.0           17  (5 → 17)
  CallbackHandler-1.0    8  (6 → 8)
  LibStub                2
