[SR] Introduce MapObjectReader

[romtsn]

#skip-changelog

Add new sentry-android-replay module## 📜 Description

• Extract an interface ObjectReader from JsonObjecteReader and introduce a new MapObjectReader analogous to what @markushi has done for the hybrid SDKs in Add API to retrieve Android scope data #2814
  • This is necessary to transform object from Maps to typed object for RRWebEvents since we hold a list of generics and lose their type at runtime.
• I also think this probably will be useful in the future if hybrid sdks will pass the data to the native ones in form of dictionaries (probably gonna be the case for Flutter session replay)

There are still some rough edges I believe, but it works for the current replay usecase, and I think it should be fine. I'll add some tests but won't cover everything (will fix stuff along-the-way if I find something).

Suggested change

	Date deserializedDate = ObjectReader.dateOrNull((String) value, options.getLogger());
	final Date deserializedDate = ObjectReader.dateOrNull((String) value, options.getLogger());
