fix(shim-sev): cleanup interrupt handling

Remove unused code from the `idt` copypasta and reduce it to the absolute minimum. As soon as `x86_64` > 0.14.6 is released, `InterruptStackFrame` and `InterruptStackFrameValue` can be removed also, see rust-osdev/x86_64#312 Signed-off-by: Harald Hoyer <harald@profian.com>
