The Early Access AppImage needs to be accessible through liftinstall, so
a couple modifications need to made:

The DIR_NAME needs to not include the revision info.
The EA AppImage name cannot contain revision info.
The EA AppImage has to be packaged with the rest of the yuzu package,
which means both binaries and the source are bundled with it now in an
archive.

In addition, fix the source archive so yuzu can actually be built from
it.

upload: Copy AppImage to both mainline and EA release package

cmake,ci: vcpkg leftovers

common: move forwarded value into SPSCQueue

audio_core: fix -Wuninitialized when compiling with ASan

ci: use dep5 for GitHub issue template files

yuzu: Add incremental steps to volume hotkeys

vcpkg: Add Catch2 2.13.9

Catch2 >= 3.0 is not compatible with earlier versions, and for now we
must override the desired version in our vcpkg manifest. We can do this
programmatically by using VCPKG_MANIFEST_FEATURES.

CMakeLists: Search for lz4 CONFIG mode first

vcpkg's lz4 CONFIG cmake script works in Release mode but not in Debug
mode, failing to copy the correct DLLs at compile time.

We still need to search for the regular mode for system-installed
versions.

CMakeLists: Clean up boost exports

Remove some Conan-specific workarounds.

CMakeLists: Use vcpkg for MSVC by default

Not enabling it generally since it's much easier to have system
dependencies installed for Linux and MinGW.

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

service: irs: Implement clustering processor

applet/swkbd: Implement optional symbol keys 

exit gracefully on sigint/sigterm

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`...

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.
