Improved keyboard handling in Conpty

Permit access to full keyboard, similar to Cygwin's raw-mode.

  ^[ [ Vk ; Sc ; Uc ; Kd ; Cs ; Rc _

       Vk: the value of wVirtualKeyCode - any number. If omitted, defaults to '0'.

       Sc: the value of wVirtualScanCode - any number. If omitted, defaults to '0'.

       Uc: the decimal value of UnicodeChar - for example, NUL is "0", LF is
           "10", the character 'A' is "65". If omitted, defaults to '0'.

       Kd: the value of bKeyDown - either a '0' or '1'. If omitted, defaults to '0'.

       Cs: the value of dwControlKeyState - any number. If omitted, defaults to '0'.

       Rc: the value of wRepeatCount - any number. If omitted, defaults to '1'.

Note:
Special handled required for mouse/bracketed-paste operations; short-term to be corrected.
Despite being CSI events, both events are re-encoded as a stream of win32-input-mode messages.

For example:

\x1b[0;0;27;1;0;1_   -> \x1b  (pressed)
\x1b[0;0;91;1;0;1_   -> [     (pressed)
\x1b[0;0;77;1;0;1_   -> M     (pressed)
\x1b[56;9;56;1;0;1_  -> 8     (pressed)
\x1b[56;9;56;0;0;1_  -> 8     (released)
\x1b[0;0;27;1;0;1_   -> \x1b  (pressed)
\x1b[0;0;91;1;0;1_   -> [     (pressed)
\x1b[0;0;77;1;0;1_   -> M     (pressed)
\x1b[16;42;0;1;16;1_ -> ???   (pressed)
\x1b[51;4;35;1;16;1_ -> #     (pressed)
\x1b[51;4;35;0;16;1_ -> #     (released)
\x1b[16;42;0;0;0;1_  -> ???   (released)
