fix(android): Keep replay capturing during animations

[romtsn]

📜 Description

Update Session Replay's PixelCopy strategy so continuously invalidating screens do not freeze after the first unstable capture. The strategy now skips only the first unstable PixelCopy/view-hierarchy pair, then resumes emitting frames while the screen keeps drawing.

Add Android sample screens for Lottie, Compose canvas, and classic View animations so the behavior can be tested manually in the sample app. The sample app remains configured to use the Canvas replay screenshot strategy.

💡 Motivation and Context

Continuous animations can cause PixelCopy output and the view hierarchy snapshot to be taken from slightly different moments. The previous debounce treated this as persistent instability and stopped emitting updated frames, which made replay visuals freeze on animated screens.

Fixes #5404

💚 How did you test it?

./gradlew :sentry-android-replay:testDebugUnitTest --tests io.sentry.android.replay.screenshot.PixelCopyStrategyTest
./gradlew spotlessApply apiDump
./gradlew :sentry-samples:sentry-samples-android:installDebug

difit staged returned no comments before the sample commit.
