[sensors_plus] Add Linux support

[12people]

Use case

While Linux is relatively new to the handheld/smartphone market, there are several devices either already out or coming out soon — most notably the upcoming Steam Deck.

It'd be great to be able to tap into the sensors for these devices.

Proposal

Add Linux support to the sensors_plus package.

Is this proposal viable aligned with the current implementation of event streams for specific sensors in the platform_interface package?
AFAIK on Linux there are iio or input device files for sensors and no userspace API, like on Android or iOS. So for Linux support we would need the possibility to specify device names at least and maybe other configuration options... Or correct me if I haven't dig deep enough in the Linux docs yet 😅
