graph-snapshots and the T1 suites run on a tablet profile too.

The chrome row asks for tablet layouts, and a tablet is a second emulator
profile rather than a test that resizes the device under itself: the job now
runs the instrumented suites twice, on a phone and on a 10.1" tablet.

For that the graph goldens had to become per device class - the same graph is
a different image at 2560x1600 - so the suite keys them by the sw600dp
boundary the layouts themselves use, and light-tablet.png now sits next to
light-phone.png. 72 goldens.

Recorded and verified on both: the tablet goldens on a tablet AVD, the phone
goldens unchanged afterwards, and the whole instrumented suite - 21 tests -
green on the tablet as well as on the phone.
