[pull] main from getsentry:main - #421

* fix(replay): Don't let a wedged video encoder freeze the app

Some hardware encoders never emit BUFFER_FLAG_END_OF_STREAM after
signalEndOfInputStream(), so SimpleVideoEncoder.drainCodec() spun forever
while holding encoderLock. ReplayCache.close() then blocked on that lock,
and since it runs inline under ReplayIntegration's lifecycleLock, the main
thread froze until the system killed the process.

Two bounds, both needed: the drain loop now gives up after 10 consecutive
no-progress iterations (~1s), and close() only waits 2s for the encoder
lock before skipping the release. The loop bound alone isn't enough --
a native dequeueOutputBuffer call can itself never return, since
ALooper::awaitResponse has no deadline of its own.

Adds AutoClosableReentrantLock.tryAcquire(timeout, unit) for the latter.

Fixes getsentry/sentry-dart#3556

* fix(replay): Log the encoder give-up at WARNING

It's an abnormal condition that drops frames, and it fires at most once
per segment, so it's worth surfacing without debug logging enabled.

* fix(replay): Address review comments on encoder ANR fix

Move isClosed.set(true) into a finally block so it runs even on unchecked
exceptions. Add a released flag to ReplayShadowMediaCodec and assert that
close() releases the encoder when the lock is available, and skips it when
timed out.
