Append UI metadata to trace file directly, instead of load+append+write
Append UI metadata to trace file directly, instead of load+append+write

Fixes: 193923003
Test: UiStateTest
Test: TrivialStartupBenchmark # verified UI metadata via Studio
Relnote: Reduce cost of appending Ui metadata to traces by 50+ ms

TIL - you can simply concatenate traces on disk, so appending got a
lot simpler.

From very simple logcat timing of TrivialStartupBenchmark, takes
average append from ~56ms to ~1ms, likely much larger difference for
longer tests.
