Increase frame capture quality, apply scaling after DPI normalization

[huntie]

Summary: Changelog: [Internal]

Updates Android screenshot capture for performance frame timings to improve image quality:

• Fix scale factor calculation by first normalizing output size based on display density.
• Increase (in most cases) output image size and encoding quality.

Impact

• Output images are now net larger (depending on DPI), and have significantly more clarity.
• Each captured frame now uses ~9x more space (vs a worst case device scaling starting point).

NOTE: These changes come with a memory tradeoff, and we may explore multi-frame sampling and a bounded buffer in future. Not a major bottleneck, even with this size increase (the bottleneck remains in expanding JS Sampling Profiler events).
