feat(mobile): add support for encoded image requests in local/remote image APIs (#26584)

Browse Source 
* feat(mobile): add support for encoded image requests in local and remote image APIs

* fix(mobile): handle memory cleanup for cancelled image requests

* refactor(mobile): simplify memory management and response handling for encoded image requests

* fix(mobile): correct formatting in cancellation check for image requests

* Apply suggestion from @mertalev

Co-authored-by: Mert <101130780+mertalev@users.noreply.github.com>

* refactor(mobile): rename 'encoded' parameter to 'preferEncoded' for clarity in image request APIs

* fix(mobile): ensure proper resource cleanup for cancelled image requests

* refactor(mobile): streamline codec handling by removing unnecessary descriptor disposal in loadCodec request
