Use efiapi for entry point

See merge request redox-os/uefi_std!5

Enable the ABI feature and use it for the entry point. This will set
calling conventions to what is specified by the UEFI spec.

It currently only sets x86-64 to `win64` and everything else to `C`.

Allow using `?` with Status again

See merge request redox-os/uefi!5

The previous change broke callers using `?` on things that returned
Status. Implement FromResidual for Result to fix it.

Also enables the `control_flow_enum` feature.
