Part of #9073.

fix(web): app/webview did not clear deadkeys on context-reset

chore(core): remove vkey output from kmx processor

chore(windows): remove unused globals relating to old keyboard debugging

chore(windows): remove legacy LoadKeyboard

Fixes #10049.

vkey output was never supported by Core, so this code effectively was a
no-op.

Fixes #10056.

Removes:
* Globals::miniContext
* Globals::miniContextIfLen
* Globals::indexStack
* Globals::msgbuf
* GLOBAL_ContextStackSize
* GLOBAL_MsgStackSize
* GLOBAL_MaxKeyboards
* INI struct (and commented-out usage of this)

Fixes #10053.

Removes `LoadKeyboard` and related functions used only by it.

chore(windows): remove `wm_keymandebug` messages and functions

Fixes #10050.

Removes the following unused identifiers:
* ::wm_kmdebug
* ::wm_keymandebug
* AppInt::DebugControlled()
* AITIP::WM_KEYMANDEBUG_CANDEBUG
* AITIP::WM_KEYMANDEBUG_GETUNICODESTATUS
* AITIP::WM_KEYMANDEBUG_GETCONTEXT
* AITIP::WM_KEYMANDEBUG_ACTION
* AITIP::WM_KEYMANDEBUG_RULEMATCH
* AITIP::DebugControlled()
* AITIP::IsDebugControlWindow()
* AITIP::GetDebugControlWindow()
* AITIP::Debug_FillContextBuffer()
* AIDEBUGINFO struct
* ::FillStoreOffsets()
* AIDEBUGKEYINFO struct

Removes overloads which are now no-ops:
* AITIP::HandleWindow()
* AITIP::IsWindowHandled()
* AITIP::QueueAction()
