Expose shared timeline counters into telemetry:

* Add UID into both shared timeline and timestats tracking: due to BLAST
APIs, layer name is insufficient for identifying applications
* Plumb through jank counters from shared timeline into timestats and WW
* Fixed bug where SurfaceflingerDeadlineMissed was not being tracked.

One caveat is that transactions are tracked in shared timeline, so as
a consequence timestats will start tracking them as well.

Bug: 171309796
Test: builds, boots
Test: statsd_testdrive
Test: libsurfacefinger_unittest
Test: dumpsys SurfaceFlinger --timestats -dump
