…meter to prevent Deep Sleep playback failures

Reason for change:
Linear and VOD playback fails after devices come out of Deep Sleep state due to stale DRM handles that are not properly released before entering Deep Sleep mode. The current stop() implementation does not provide a mechanism to force DRM handle cleanup, leading to tune failures with stale DRM sessions after device wake-up.

Changes done:
- Enhanced PlayerInstanceAAMP::Stop() API with optional forceCleanup parameter (default false)
- Added DRM session cleanup logic using licenseManager->clearDrmSession(forceClearSession) and clearFailedKeyIds()
- Updated JavaScript bindings to support both single parameter stop(forceCleanup) and two parameter stop(sendStateChangeEvent, forceCleanup) forms
- Modified jsmediaplayer.cpp to handle argument parsing for backward compatibility
- Updated UVE API documentation with usage examples for Deep Sleep scenarios
- Enhanced mock files and test infrastructure to maintain compatibility
- Added comprehensive logging for debugging Deep Sleep DRM cleanup operations

This allows applications to call player.stop(true) before Deep Sleep to proactively clean up DRM resources and prevent playback failures after wake-up.

Test Procedure:

Priority: P2

Risks:Low
