Makoto Kato 1be11f4ee1 Bug 1556983 - Primary pointer capability should be coarse when having touch screen. r=geckoview-reviewers,agi
Many users report that GeckoView returns non-coarse value for primary pointer
capabilities. Actually, we assume that primary pointer device is 1st device by
`InputDevice.getDeviceIds`, but some mobile devices seems not to return touch
screen as 1st item according to user reports.

Also, Android's `InputDevice` API doesn't define what is primary pointer
device, so we cannot assume primary pointer device well.

Other implements are,

- Chrome returns coarse if something input device has coarse capability.
- Firefox for Windows seems to return coarse if it is tablet mode.

So we should return coarse as primary pointer capability when having touch
screen, like Chrome.

But there is still another issue.

When I check some devices (including Android VM on Chrome OS), even if no touch
screen, the `InputDevice`'s source may has `SOURCE_TOUCHSCREEN`. Chrome checks
that fine pointer at first, then it checks coarse pointer. But current GV is
coarse pointer at first. Since the `InputDevice`'s source may have both
`SOURCE_MOUSE` and `SOURCE_TOUCHSCREEN` on touchpad/mouse, GV returns different
result. So we shouldn't check `SOURCE_TOUCHSCREEN` at first.
