fix(replay): Do not use recycled screenshots

[romtsn]

📜 Description

• Sometimes we were using a recycled bitmap for masking (e.g. if recorder.close() is called from a different thread after we captured the screenshot, but before masking is applied) which resulted in native crashes when initing a Canvas backed by it. This PR checks for bitmap.isRecycled and recorder being closed before doing anything with the screenshot.
• Added ReplayExecutorService which allows us to abstract away our "safe" way of submitting runnables, but also allows us to override this behaviour in tests in case we want a test to actual fail because of the exception thrown inside runnable.

💡 Motivation and Context

Closes getsentry/sentry-react-native#5159
