nvcodec: Refactor plugin initialization
Create CUDA context per device, instead of per codec and encoder/decoder.
Allocating CUDA context is heavy operation so we should reuse it
as much as possible.

vulkan/window/win32: Don't post any WinProc message to parent window
Posting any message to parent seems to be pointless. That might break
parent window.
Regardless of the posting, parent window can catch mouse event
