Support high-resolution scroll

VirtualMouse currently supports -1f to 1f float scroll values,
but it worked for integer values only as input framework supported
only REL_HWHEEL and REL_WHEEL events. With the introduction of
high-res scroll event support (REL_HWHEEL_HI_RES and REL_WHEEL_HI_RES),
granular mouse scrolling can be done, and VirtualMouse scroll API
would work for all float values.

Flag: android.companion.virtualdevice.flags.high_resolution_scroll
Test: atest VirtualMouseTest
Bug: 335160780
