[FSSDK-12510] fix old test issues with mockito versions

[jaeopt]

Fix instrumentation tests on Android API 28+

Problem

• TransactionTooLargeException crashed the android-sdk test process when 262+ test results were bundled into a single IPC parcel exceeding Android's 1MB limit
• Mockito cannot mock this class failures on API 28+ because the default mockito-android mock maker uses a hidden/restricted API (BaseDexClassLoader#addDexPath()) blocked since API 28
• Root cause of Mockito failures: PR Upgrade targetSDK to 35 #516 (targetSDK 35 upgrade) downgraded mockito_ver_sdk_module from 3.6.28 → 2.28.2, which is too old to work with dexmaker-mockito-inline

Changes

• Revert mockito_ver_sdk_module back to 3.6.28
• Add dexmaker-mockito-inline:2.28.3 to all 6 modules — uses JVMTI bytecode rewriting instead of restricted APIs, works on API 28+
• Add Android Test Orchestrator to android-sdk module — runs each test class in its own process, preventing parcel overflow as the test suite grows
• Pin objenesis:2.6 to maintain API 21 compatibility (objenesis 3.x requires API 26+)
• Set testCoverageEnabled false in all modules to avoid JVMTI agent conflict between Jacoco and dexmaker

Test plan

Existing tests will cover the changes.
