Add event timestamps for controller events

[slouken]

We now have the ability to pass on event timestamps from the OS, added in https://github.com/libsdl-org/SDL/commit/0a3262e819edc695a764702e8127bbd1b09944ef.

Some controllers have a timestamp in their report, which is currently used for the sensor timestamp. Let's remove the sensor timestamp and fill in the timestamp of the events with that information.

From https://github.com/libsdl-org/SDL/issues/1000#issuecomment-1335836230: Nice! For some of the (non-SDL) games I've worked on we've heavily used timestamps from gamepad thumbstick events for high precision and accuracy with some analog aiming controls. Now that this is implemented for some systems I think hooking it up for joysticks would be worthwhile in the future, if it hasn't already been considered.

For example Microsoft's GameInput API has a timestamp feature.

so close

I made this change and then backed it out, because when you're integrating sensor timestamps over time you need the precision of the hardware clock in the sensor, rather than introducing error when we try to synchronize with the system clock.
