feat: OutputDevice build support for Linux

[UE4SS]

Description

This PR adds some support for DynamicOutput.
I've decided a iterative method of adding Linux support may be more effective than doing it all in one chunk, so I might make more PRs similar to this with small-ish changes for Linux support.

Fixes # (issue) (if applicable)

Type of change

• Other... Please describe: Build support for Linux

How has this been tested?

This has minimal testing.
Specifically, running UE4SS on Windows has been tested and still works, and using DynamicOutput on Linux has been tested and is working except FileDevice and NewFileDevice. Nothing else has been tested.
The File dependency on Linux is not implemented.

It's tested by making a program that utilizes each dependency independently of UE4SS.
CMakeLists.txt, manually change platforms by un/commenting the line near the bottom of the file.

This patch is also required if you want to test this on Linux.
It will be added as part of a later PR when Linux is more ready to be used.
