Turns out that for Qt to properly handle plurals in English a
translation needs to be provided, otherwise the user is left with
messages such as "Building: 2 shader(s)"

Plurals for other all other languages are handled on transifex.
I wrote the README.md to just refer to it as a translation
collaboration site just in case we ever switch.

These translations being out of date won't pose any technical problems
so I believe it is fine to handle them manually on a "best effort"
basis.

The files are generated into the source directory so that the
relative filenames are correct. The generated file is added to
.gitignore

yuzu: Add incremental steps to volume hotkeys

Revert "ci: Enable building with Visual Studio 2022"

externals: Use yuzu-emu/discord-rpc to provide Discord integration

Our fork includes a commit to disable clang-format, preventing the dirty
flag from being set when building yuzu on CI.

[Audio] Avoid an out-of-bounds span write in depop prepare

ci/linux: Exclude libwayland-client from AppImage

build: Ship vcpkg dlls with MSVC pr-verify builds

gpu_thread: Use the previous MPSCQueue implementation

chore: make yuzu REUSE compliant

As mentioned in the previous commit, `reuse lint` can be used to ensure
that copyright information is always present and up to date.

This adds a GitHub Action that does just that, using the official
fsfe/reuse-action

[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.

Follow-up to 01cf05bc

With our recent switchover from conan to vcpkg, we're shipping a few
more dll files, these need to be in the full zip.

    cp .\build\bin\*.dll .\artifacts\

also tacking on the fix where we're shipping scm_rev.cpp accidentally

externals: Use GitHub for FFmpeg

FFmpeg's own git repo seems to be down, so switch to GitHub like we use
for most externals.

This library causes issues in Vulkan driver detection.
libQt5MultimediaGstTools's dependencies seem to be the issue.
