Chris Bracken 82cd793ee5 Use iOS scale when computing render buffer size (#4171) (#4373) ...

When checking whether render buffer size has changed, apply the device
scale factor used to convert points to pixels to ensure we're not
needlessly re-allocating render buffer storage.

Adds trace + debug log to make this easier to detect in future.

Originally introduced in 2d530daeca, but
rolled back in 0a6e415b60 to test whether
it was responsible for regressions to
flutter_gallery_ios__transition_perf benchmarks:
  * average_frame_build_time_millis
  * missed_frame_build_budget_count

Re-landed in d43d353475, and reverted in
459f722b86 after it appeared to regress
the above two benchmarks. After recent changes to microtask execution
order which fixed https://github.com/flutter/flutter/issues/9998,
re-introducing this fix results in benchmark improvements to the above
two benchmarks in local testing.
