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

vulkan_common: declare storageBuffer8BitAccess

spirv_emit_context: declare GroupNonUniform capability for SubgroupLocalInvocationId

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

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.

We need this.

Wayland does not allow clients to choose their own size and position
on the screen. The concept of fullscreening an application by sizing
it to the screen and removing decorations does not exist. Use
exclusive fullscreen instead.

Some windowing systems like wayland are designed to show hardware accellerated
surfaces as subsurfaces and not native windows.

Use SDL_GL_GetDrawableSize instead of SDL_GetWindowSize which
will return the true size our swapchain needs to be in even
for hidpi displays.

Vulkan for whatever reason does not return VK_ERROR_OUT_OF_DATE_KHR when
the swapchain is the wrong size. Explicity make sure the size is indeed
up to date to workaround this.
