Hide Power devices from Power menu with underscore in the name

[nppc]

Requested feature:

If I add underscore (_) in front of the power device name, then it will not appear in the drop-down menu under the power button at right top corner.

Similar is made for Macros already.

Solves the following problem:

I have multiple devices connected to host on different pins. There is some prerequisites, when I can turn devices on or off, so they should not appear under Power menu. With physical button (also connected to the host pin) I change the state of host pins defined as power devices. This is done with on_press event of the button with machine.device_power.post_device power API.

Additional information:

Maybe it could be done with virtual mcu on host, but it looks like overkill to run a virtual mcu to do this small job.

Thx for your FR. I just forgot to add it to the power devices.
