Expand gpu1 tests to all devices on API 34 & 35

Updates the gpu1 workflow to test all available Android devices
(Pixel 6, Pixel 6 Pro, Pixel 7, Pixel 7 Pro, and Generic Tablet)
on API levels 34 and 35, including Google Play versions where applicable.

This expands coverage from 4 jobs to 14 jobs to ensure comprehensive
testing across the full device matrix supported by gpu1.
