chore: make yuzu REUSE compliant [REUSE] is a specification that aims at making file copyright information consistent, so that it can be both human and machine readable. It basically requires that all files have a header containing copyright and licensing information. When this isn't possible, like when dealing with binary assets, generated files or embedded third-party dependencies, it is permitted to insert copyright information in the `.reuse/dep5` file. Oh, and it also requires that all the licenses used in the project are present in the `LICENSES` folder, that's why the diff is so huge. This can be done automatically with `reuse download --all`. The `reuse` tool also contains a handy subcommand that analyzes the project and tells whether or not the project is (still) compliant, `reuse lint`. Following REUSE has a few advantages over the current approach: - Copyright information is easy to access for users / downstream - Files like `dist/license.md` do not need to exist anymore, as `.reuse/dep5` is used instead - `reuse lint` makes it easy to ensure that copyright information of files like binary assets / images is always accurate and up to date To add copyright information of files that didn't have it I looked up who committed what and when, for each file. As yuzu contributors do not have to sign a CLA or similar I couldn't assume that copyright ownership was of the "yuzu Emulator Project", so I used the name and/or email of the commit author instead.

Common: Remove async logging It provided a large increase in complexity of the logging system while having a negligible performance impact: the usage patterns of the ring buffer meant that each log contended with the logging thread, causing it to effectively act as a synchronous extra buffering. Also removed some broken code related to filtering of subclasses which was broken since it was introduced. (Which means no one ever used that feature anyway, since, 8 months later, no one ever complained.)

logging: Simplify and make thread-safe This simplifies the logging system. This also fixes some lost messages on startup. The simplification is simple. I removed unused functions and moved most things in the .h to the .cpp. I replaced the unnecessary linked list with its contents laid out as three member variables. Anything that went through the linked list now directly accesses the backends. Generic functions are replaced with those for each specific use case and there aren't many. This change increases coupling but we gain back more KISS and encapsulation. With those changes it was easy to make it thread-safe. I just removed the mutex and turned a boolean atomic. I was planning to use this thread-safety in my next PR about stacktraces. It was actually async-signal-safety at first but I ended up using a different approach. Anyway getting rid of the linked list is important for that because have the list of backends constantly changing complicates things.

Refactor Logging Impl Loop on stop_token and remove final_entry in Entry. Move Backend thread out of Impl Constructor to its own function. Add Start function for backend thread. Use stop token in PopWait and check if entry filename is nullptr before logging.
