Subject: Add movement hook to ps2_mouse (#8805)

Process mouse movement in the keymap before it is sent to the host. Example uses
include filtering noise, adding acceleration, and automatically activating a
layer. To use, define the following function in your keymap:

void ps2_mouse_moved_user(report_mouse_t *mouse_report);
