This change introduces a new API getTopPageObjectAtPosition to the PdfDocumentRemote interface to query the topmost PDF object at a specific point on a page, filtered by object type.

- A new PdfObject AIDL parcelable.
- The getTopPageObjectAtPosition method in PdfDocumentRemote.aidl

This change introduces the getTopPageObjectAtPosition functionality to the PdfDocument interface.

includes:
- Adds the new getTopPageObjectAtPosition suspend function to the PdfDocument interface.
- Implementation in SandboxedPdfDocument`.
- Adding placeholder implementations in various FakePdfDocument and FakeEditablePdfDocument classes used for testing.

This change implements the conversion from the AOSP `PdfPageObject` to the Jetpack `PdfObject` within `PdfDocumentRemoteImpl`.

- The `getTopPageObjectAtPosition` function now converts the AOSP `PdfPageObject` and `PdfPageImageObject` into the corresponding Jetpack `ImagePdfObject`, `PdfObject`
- The bounding box for `ImagePdfObject` is calculated from the transformation matrix of the `PdfPageImageObject`.

… AudioSpec

 The 'AUTO' naming was ambiguous in cases where the system needed to distinguish between "automatically selected" and "no preference provided." Transitioning to 'UNSPECIFIED' improves semantic clarity for configurations where no specific requirement is set, allowing the resolution engine to handle defaults more predictably.

Key changes:
- Renamed QUALITY_SELECTOR_DEFAULT to QUALITY_SELECTOR_UNSPECIFIED in VideoSpec and initialized it with a new QualitySelector.NONE constant.
- Moved DEFAULT spec instances from MediaSpec companion object to their respective classes (VideoSpec.DEFAULT and AudioSpec.DEFAULT) for better encapsulation.
- Updated Recorder.DEFAULT_QUALITY_SELECTOR to explicitly define its preferred quality list (FHD, HD, SD).
- Removed unused AudioSpec.NO_AUDIO.

 Introduce MediaConfigUtil to centralize the logic for resolving media settings (container format, MIME types, and EncoderProfiles), including the auto-selection via FormatComboRegistry queries if certain container format or MIME types are unset.

 Currently, `VideoConfigUtil.resolveVideoMimeInfo()` and `AudioConfigUtil.resolveAudioMimeInfo()` resolve settings based only on output format and EncoderProfiles. However, supporting custom MIME types requires evaluating the entire combination of MediaSpec(container, MIME types), DynamicRange and EncoderProfiles. `MediaConfigUtil.resolveMediaInfo()` will later replace the `VideoConfigUtil.resolveVideoMimeInfo()` and `AudioConfigUtil.resolveAudioMimeInfo()` to handle these combinations holistically.

 Key changes:
 - Added `MediaConfigUtil.resolveMediaInfo()` which attempts to resolve configuration using `EncoderProfiles` first, and falls back to `FormatComboRegistry` if necessary.
 - Introduced `MediaInfo` class to aggregate the resolved configuration (Container, Video, Audio).
 - Added `ContainerInfo` to hold container format details.
 - Added helper methods in `VideoConfigUtil` and `AudioConfigUtil` to resolve compatible profiles based on MIME types and dynamic range.

  Centralize media configuration resolution with MediaConfigUtil
  Refactor: Rename *_AUTO to *_UNSPECIFIED in MediaSpec, VideoSpec, and AudioSpec

This CL refactors UseCaseCameraRequestControl to support lazy
initialization, moving its heavy construction off the main
thread during camera startup.

DeferredUseCaseCameraRequestControl:
A proxy implementation that intercepts control requests and
dispatches them to the background sequential thread before
initializing the real implementation.

Updated UseCaseCameraRequestControlImpl: Modified internal
dispatching logic (runOnSequential) to detect if it is already
running on the sequential thread. If so, it executes immediately
(using CoroutineStart.UNDISPATCHED) to prevent double-posting tasks.

Binds the new Wrapper to the UseCaseCameraRequestControl interface,
allowing consumers (like FlashControl, ZoomControl) to remain
unchanged while benefiting from lazy loading.
