feat: use jnigen for android

[josxha]

Overview

• [x] generate bindings using jnigen
• [x] integrate into the MapController
• [x] replace some pigeon functions with jni
• [x] fix web compilation errors
• [x] fix proguard for release builds
• [x] bump min flutter version to 3.24.0 (min dart version to 3.5.0) because meta ^0.15.0 is required by jni.
