[SR] Flutter improvements

[romtsn]

📜 Description

• Adds a flag to disable configuration change tracking, as Flutter has its own hooks for that and will call replay.onConfigurationChanged accordingly
• Make frameRate and bitRate for the video encoder lazier, i.e. we pass those everytime we want to generate a video instead of storing them in the class member (as part of the recorderConfig)

💡 Motivation and Context

Closes #3951
Part of getsentry/sentry#74441

💚 How did you test it?

manually + automated

📝 Checklist

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

if you mean inside ReplayCache it's for the case when RecorderConfig changes after we create a ReplayCache instance, so we always use the latest known values for frameRate and bitRate
