Duplicate Objective-C classes in bundled frameworks

Description of Issue

- At every launch, the Objective-C runtime warns that several classes are implemented in two of Lightroom's bundled frameworks. Apple documents this as able to "cause spurious casting failures and mysterious crashes".

- The app bundle also contains a second, complete copy of WichitaFoundation (19 MB) inside AgUI.framework that is never loaded, and a category (NSException(ToString)) defined in both AgKernel and AgSubstrate, where which implementation wins is undefined and the runtime doesn't warn.

Step-by-step Reproduction Instructions

1. Launch Lightroom.

2. Open the first lines of:
   ~/Library/Containers/com.adobe.mas.lightroomCC/Data/Library/Application Support/Adobe/Lightroom CC/lrcc_console.log

3. Optional, without launching Lightroom (Xcode command line tools): list the Objective-C classes each framework defines and compare, e.g.
   cd "/Applications/Adobe Lightroom.app/Contents/Frameworks"
   xcrun dyld_info -arch arm64 -objc WichitaFoundation.agtoolkit/Versions/A/WichitaFoundation | grep "@interface"
   xcrun dyld_info -arch arm64 -objc CameraRaw.lrtoolkit/Versions/A/CameraRaw | grep "@interface"

4. Compare the two WichitaFoundation copies and check which one AgUI links to:
   dwarfdump --uuid WichitaFoundation.agtoolkit/Versions/A/WichitaFoundation AgUI.framework/Versions/A/Frameworks/WichitaFoundation.agtoolkit/Versions/A/WichitaFoundation
   otool -L AgUI.framework/Versions/A/AgUI | grep WichitaFoundation
   lsof -p $(pgrep -x "Adobe Lightroom") | grep WichitaFoundation

The Expected Result

- Each class is defined in exactly one framework, or namespaced per framework, with no runtime warnings

- Each category method is defined once

- The app bundle contains one copy of each framework

The Actual Result

- objc: Class SODSFileDecode is implemented in both …/WichitaFoundation.agtoolkit/…/WichitaFoundation and …/CameraRaw.lrtoolkit/…/CameraRaw. This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed.

- The same warning for _GPUOperator and _CPUOperator (WichitaFoundation and CameraRaw), and for VFExporterMessageDelegate, VFTools and VFExporter (CameraRaw and video_toolkit.agtoolkit).

- A static check of all 35 binaries in the bundle (xcrun dyld_info -objc) finds 37 classes or categories defined in more than one binary:
  - the six above;
  - NSException(ToString), a category in both AgKernel and AgSubstrate;
  - 30 classes shared by Frameworks/WichitaFoundation.agtoolkit and a second copy at Frameworks/AgUI.framework/Versions/A/Frameworks/WichitaFoundation.agtoolkit (19 MB, same arm64 UUID A433F2B5-42A7-3B02-9151-9D9F13069C06). AgUI links to @executable_path/../Frameworks/WichitaFoundation.agtoolkit, and lsof on a running Lightroom shows only the main copy open, so the nested copy is never used.
