Make wxEVT_CHAR_HOOK propagate upwards and send it to the window itself.

Send wxEVT_CHAR_HOOK events to the focused window itself but make them
propagatable to ensure that the parent windows (including the top level
parent) still get it. This still allows the TLW parent to intercept keyboard
handling in its child but allows the child (or an intermediate parent window)
to have some say in the matter.

See #9102.
