AssetBundle build performance has regressed when building in batchmode with Metal

How to reproduce:

1. Run the attached project “IN-148516” in batchmode with “-executeMethod MeshReproBuild.BuildBundles” argument
2. Observe the time it takes to build the AssetBundles

Actual result: The build time in later Editor versions is the same or similar to 6000.0
Expected result: The build takes more than 50% longer than on 6000.0

Reproducible with: 6000.3.17f1
Not reproducible with: 6000.0.75f1

Reproducible on: macOS 25.5.2 (M5 Max) (by reporter)

Notes:

• Not reproduced by CQA on macOS 25.5.2 (M4 Max)
• Adding “-nographics” restores original build time
• IOGPUResourceCreate count is much larger on the affected version
