Attachment: Create hidden native caret for ATOK at composing in windowless plugin

I think that the strict approach to fix this bug is hooking ::CreateCaret(), ::DestroyCaret() and ::SetCaretPos() if this works without sandbox. However, this approach may increase the number of additional IPC.

So, I think that it's more reasonable to create native caret at setting candidate window position and guess the size.
