Shadow flickering on remeshing

## Bevy version and features
bevy 0.17.2
default features + "bevy_dev_tools"

## Relevant system information
SystemInfo { os: "Windows 11 Home", kernel: "26100", cpu: "AMD Ryzen 7 9800X3D 8-Core Processor", core_count: "8", memory: "61.6 GiB" }
AdapterInfo { name: "NVIDIA GeForce RTX 2080 Ti", vendor: 4318, device: 7687, device_type: DiscreteGpu, driver: "NVIDIA", driver_info: "581.08", backend: Vulkan }

You should also consider testing the examples of our upstream dependencies to help isolate any setup-specific issue:

## What you did
Created some procedural meshes, re-meshing chunks of voxels and updating the mesh.

## What went wrong
Shadows flicker/disappear/re-appear, mostly when re-meshing it seems.

## Additional information
I am running at a relatively high FPS, 240+, I don't encounter this issue on my M1 macbook pro, so it could be OS/platform based or it could be some niche timing issue here.

Start by reproducing the reported shadow flickering while procedurally remeshing voxel chunks on Windows 11 with Vulkan, using Bevy 0.17.2 and the default features plus bevy_dev_tools. Compare the behavior with the M1 macOS result and investigate the possible relationship to issue #21632; done means the cause is isolated and the flickering is fixed or clearly documented.
