hwdb: add MOUSE_WHEEL_TILT_VERTICAL/HORIZONTAL to the mouse db (#5023)

Browse Source 
Plenty of single scroll-wheel mice have the ability to tilt the wheel to
generate horizontal wheel events. They use the same evdev axis as a real
horizontal wheel (REL_HWHEEL) and are indistinguishable to userspace from the
real thing. libinput promises physical degrees for wheel events but that's not
accurate for those tilting wheels, hence mark them as tilting wheels so we can
treat them like the special snowflakes they think they are.

#
# Indicates that the respective axis is not a mouse wheel rotation but a
# tilt along that axis. Wheel tilt is most commonly used for horizontal
# scroll wheel emulation on mice with only a single vertical wheel.
#
# The vertical and horizontal Axes are independently marked as tilt axes,
# for example it is permitted to have a MOUSE_WHEEL_CLICK_COUNT or
# MOUSE_WHEEL_CLICK_ANGLE for the vertical axis and mark the horizontal axis
# marked as as MOUSE_WHEEL_TILT_HORIZONTAL.
#
# It is a bug to have either CLICK_COUNT or CLICK_ANGLE set on the same axis
# as WHEEL_TILT. Applications should give priority to WHEEL_TILT and ignore
# other settings.
#
# This is a flag only, permitted values: 0 or 1
#
# Sort by brand, type (usb, bluetooth), DPI, frequency.
# For mice with switchable resolution, sort by the starred entry.
