feat: Add HPET configuration from Atomic Studio

[EPOCHvoyager]

I have to preface this by stating that I do not understand the underlying mechanisms adequately myself - but after speaking to the Atomic Studio dev last month, I'm told this tweak might help those facing audio issues, particularly on constrained handhelds - and that it should have no ill effect otherwise.

Atomic Studio currently implements it here.

Do note that this is my first technical PR, and that as such this might not be the proper or preferable way of implementing this.

@tulilirockz you might be able to give more insight in this for us as to how this works and help.

This is not needed when you add the file in the desktop image, as the deck image is built from the desktop image and get the file through that.
If we needed the number to be different for the deck image then this file would be needed.

Alright, good to know! Sending in another commit to fix this.

Cool I could approve that, shouldn't I be a maintainer or something? :-D
But fixing audio issues is always nice :-)

After having talked to @tulilirockz about the details of this, i don't think i will be approving this as it would increase power consumption (and the desktop image is also used on laptops) and battery drain for little to no gain for gaming audio.

They also mentioned that if this did get merged, make sure it does not get included in the -deck images.

I think this instead would make more sense as a ujust command, that way it is optional and we can also throw in a warning that it will increase power consumption.
The difference in location then is just that you write the file to /etc/sysctl.d/ instead using bash in the justfile.
