[gpio/samples/simgpio]: Gpio sample uninstall break when driver verifier on

@yinghany is already working on this.

Since Aug 19, 2026.

### Which is the area where the sample lives?

/gpio/

### Describe the issue

- The simgpio driver will make windows system enter nt!DbgBreakPoint when uninstall the driver with driver verifier on.

- Target windows arm64 version:

```
Edition Windows 11 Pro
Version 25H2
Installed on ‎4/‎1/‎2024
OS build 26200.8037
Experience Windows Feature Experience Pack 1000.26100.300.0

- Install simgpio driver by pnputil command on target windows system: pnputil /add-driver simgpio.inf /install
- Enable driver verifier for this driver: verifier /standard /driver simgpio.sys
- Reboot system to make verifier work
- Try to uninstall simgpio.sys by pnputil command: pnputil /delete-driver oem1.inf /uninstall
- And we can see the following call stack in WinDbg, it seems that msgpioclx module try to get interrupt resource from Wdf01000 module resource but failed:
