  Log Message:
  -----------
  MdeModulePkg: Correct Usb Mouse Z for absolute pointer.

https://www.usb.org/sites/default/files/hid1_11.pdf
Appendix B, B.2 Protocol 2 (Mouse) details the information
returned by a usb mouse HID.

bytes 3..n are specific to the device, but are used by absolute
pointer devices to return a z axis.

Prior to this change, the existing code was reusing the X value for
the Z axis, which was incorrect.

For usb devices which do not return enough data for a z axis,
this change will be a no-op.
