[FSSDK-11875] chore: add support for android 15 (#84)

* build: update Android build configurations

- Bump compile SDK version to 35 and build tools version to "35.0.0"
- Update target SDK version to 35
- Add namespace 'com.optimizely.optimizely_flutter_sdk'
- Enable buildConfig feature
- Update kotlin-stdlib-jdk7 to version 2.1.0
- Update jackson-databind to version 2.17.2
- Set minSdkVersion and targetSdkVersion to 35 for example app
- Update distributionUrl in gradle-wrapper.properties to Gradle 8.10.2
- Update android plugin version to 8.7.0 and kotlin-android version to 2.1.0

* build: update Android SDK versions

- Update compile SDK version to 36 and build tools version to "36.0.0"
- Change min SDK version to 21 and target SDK version to 36 in the Android build configuration
- Update compile SDK version to 36 and target SDK version to 36 in the example app build.gradle file

* fix: update android build configuration

- Update compile_sdk_version and build_tools_version to 35
- Remove target_sdk_version from ext
- Update compileSdkVersion and targetSdkVersion in app/build.gradle to 35

* refactor: update compile and target SDK versions

- Update compile SDK version to use project property if available, fallback to default
- Update target SDK version to use project property if available, fallback to default

* fix: remove conditional expressions for compileSdkVersion and targetSdkVersion

- Simplify specifying compileSdkVersion and targetSdkVersion directly from flutter configuration
