Log some data when the QS panel starts expanding
The main goal is to learn at what x-position users tend to swipe down to
pull the notification/qs shade. To do that, this CL logs the following
data:
- x-location (as 0-100 percent)
- y-location (same)
- device rotation
in PanelView#startOpening(). This should only be logged rarely enough
(once per qs pull) not to spam logs or have any performance impact.
It also currently doesn't collect any data when expanding qs from the
keyguard, but I'm assuming that that particular case is much less
common. Logging could be added later though.
Fixes: 74012876
Test: adb logcat -b events | grep sysui_multi_action; pull notification
shade when device is unlocked and see lines like this:
02-28 12:41:42.060 31783 31783 I sysui_multi_action: [757,1324,758,4,826,413,827,12769,1322,91,1323,0,1325,0]
