Make Surface::present() errors non-fatal.

[vorporeal]

Description

WISOTT.

We need this in order to be able to catch device loss errors using an error scope and handle them gracefully.

Testing

• Tested by adding the following code at the start of present() that unconditionally produces a DeviceError::Lost and verified that Warp will detect it and try to recreate the renderer.

let error = SurfaceError::Device(wgc::device::DeviceError::Lost);
self.context
    .handle_error_nolabel(&self.error_sink, error, "Surface::present");
