BGL resource type mismatches not handled correctly for render bundles #8038
Description
Validation for render bundles does not have parity with that of render passes, incorrectly allowing mismatched bind groups to be passed to the underlying platform. This can be reproduced with cargo xtask 'webgpu:api,validation,encoding,programmable,pipeline_bind_group_compat:bgl_resource_type_mismatch:*'.
- On Vulkan, this emits a warning, and keeps going.
- On DX12, the runtime crashes.
- I have not checked how this behaves on macOS.
