Improve CI (#345)

* Don't upload artifacts unless on main

* Fix if/endif mismatch warning

* Add thirdparty CMakeLists

* Keep more warnings around

* Remove more RakNet warnings

* Fix indentation and divided the cmake into libraries and bins

- Each library and binary got their own CMakeLists.txt
- Indentation was fixed everywhere
- Weird if statement flows replaced

* Revert "Fix indentation and divided the cmake into libraries and bins"

This reverts commit 005a12424e.

* Add async value assignments

Resolves a warning where on some compilers this thread would _not_ be run async and would instead be run synchronous with the main thread, halting execution.

* Revert "Add async value assignments"

This commit was meant to be done on a seaparate branch but was accidentally pushed upstream to this branch.

* Fix Merge Conflict

* Resolve errors

Resolve errors with using continue() outside a foreach loop.

* breakout mariadb to thirdparty cmake

Move the mariadb cmake to its own directory to make each cmake file more focussed.
