Our "painful" `Error::Internal(String)` design for useful errors makes
it impossible for downstream crates to retrieve the original `HRESULT`
and match on it as necessary to action on stringified error codes like
`DXGI_ERROR_DEVICE_REMOVED`, which print:
ID3D12Device::CreatePlacedResource failed: The GPU device instance has been suspended. Use GetDeviceRemovedReason to determine the appropriate action. (0x887A0005)
Without rearchitecting our `Error` type, the nicest middle ground
is anyway for `gpu-allocator` to already add the error message from
`GetDeviceRemovedReason()` to the `Result` so that downstream crates
can immediately see in their error messages _why_ the device is or was
removed/suspended when they make an allocation.
