input_common: Add virtual gamepad

Vulkan: Add support for VK_EXT_depth_clip_control.

qt: avoid setting WA_DontCreateNativeAncestors on all platforms

qt: handle wayland-egl platform name

camera: Use pre-allocated vector for camera data

hle_ipc: Refactor ReadBuffer to set buffer size upon initialization

[audio_core] Signal buffer event on audio in/out system stop

Remove unimplemented geometry transform feedback log spam

And avoid an unnecessary copy

Set: Allow setting device nickname

hle_ipc: Reserve vectors before populating

let games gracefully exit

yuzu qt, common: Add option to create game shortcuts on Linux

Initializing the vector size during initialization is more efficient than a later call to resize()

vulkan_common: declare storageBuffer8BitAccess

spirv_emit_context: declare GroupNonUniform capability for SubgroupLocalInvocationId

Used by Just Dance® 2023 Edition

build: tweak the find modules even more

Wayland fixes

As described in
https://github.com/yuzu-emu/yuzu/pull/9395#discussion_r1047456172
checking for PKG_CONFIG_FOUND before calling pkg_search_module() is
unneeded, and some find modules (like FindFFmpeg.cmake) don't do this
already. Consequently, this patch removes these checks.

Revert "hle: service: audio: Use default service thread."

render_vulkan: Fix validation errors on less compatible Intel GPUs

Moves icon path to ~/.local/share/icons, though I'm opting to avoid
using the game title for the icon and desktop entry name as that would
cause filenames such as
"yuzu-cadence-of-hyrule-crypt-of-the-necrodancer-featuring-the-legend-of-zelda-demo.desktop".

This creates a Desktop Entry file and a PNG icon for the entry when the
user right-clicks a game and selects "Create Shortcut -> Create
{Application,Desktop} Shortcut". This uses the current executable's path
to create the shortcut.

yuzu qt: Add more error checking and OS gating for shortcuts

main: Remove FreeBSD gating for shortcuts

I'm not going to test FreeBSD, so I don't know if they follow
Freedesktop.org or not. I just have to let someone else verify that it
works there and let them enable it.

main: Move shortcut function to its own function

This function should really be in a common library, at least among
frontends.

main: Remove image manip references

main: Fix difference in MinGW and native GCC versions

main: Fix negation in creat shortcut

main: Re-enable freedesktop shorcuts for FreeBSD

Instead of checking a environment variable which may not actually
exist or is just wrong, ask QT if it's running on the wayland
platform.
