Description
For 0.15 and later, the shadow example doesn't render the cubes nor shadows, only the plane. The problem is expanded on in bevy bevyengine/bevy#8037, where it only shows the clear color and sometimes UI. The shadow example was just what I used to find where the problem was in the update from 0.14.0 to 0.15.0.

Repro steps

1. Find an intel laptop with an integrated GPU
2. Make sure the graphics driver is relatively old (one I'm using is from June 2021)
3. Run the shadow example in a version of wgpu 0.15 and later

Extra materials
The problem comes from 39f6b03 / #3327

Removing this snippet of code fixes the bevy issue and the shadow example:

I have no idea why, so I wanted to ask if anyone has any ideas on why VK_EXT_robustness2 causes almost everything to not be rendered in vulkan, yet be fine with a more recent driver or a different GPU. A couple thoughts I got was perhaps:

• "could be that Intel screwed up the implementation of that extension"
• "maybe an alignment issue? 'It is important to query the robustUniformBufferAccessSizeAlignment and robustStorageBufferAccessSizeAlignment from VkPhysicalDeviceRobustness2PropertiesEXT as the alignment of where buffers are bound-checked is different between implementations'"

I'm sure this extension is useful to have, so I don't want to add a PR removing it for all GPUs, and am currently unaware of how best to add an exception for outdated intel iGPU drivers.
