[PATCH 1/6] user32: Add nulldrv dummy english keyboard layout.

This supersedes 203899-203901 in a sense that they will conflict with
the patches. The previous series was anyway not doing much and I intend
to resend the surface patches later, making all user32 tests pass with
null driver progressively.

As a starting point, this series makes all the user32 input tests pass
with null graphics driver.
