[KERNEL32]

[KERNEL32]
- Simplify IntGetConsoleInput and IntReadConsole.

[CONSRV]
- Implement event waiting for reading console input buffer with CSR wait blocks. This replaces the event-based waiting which, after being moved from client-side (kernel32) to server-side (see r57721), made all consoles hang when one of them was waiting for new input.

TODO: Dereference all the waits in Console->ReadWaitQueue.
