InputCommon: Add multiple udp server support

InputCommon: Fix implicit conversion in mouse input

vk_shader_decompiler: Implement force early fragment tests

Disable web applet and warning box when compiling for Linux on CI

yuzu's web applet does not or barely reacts to user input while open in
Linux. It can be closed via 'Exit Web Applet' on the menubar, however if
yuzu is in fullscreen, this is effectively a softlock as the menubar
cannot be accessed.

This disables building yuzu with the web applet on the Linux CI target.
In addition, this disables the QMessageBox warning about not having
compiled yuzu with the web applet.

InputCommon: Implement full mouse support

common: Add Common::DivCeil and Common::DivCeilLog2

hid: Check if applet_resource exists in InitializeVibrationDevice

Add missing types to NpadCommunicationMode

HID: Stub set and get NpadCommunicationMode

audio_core: Remove temp_mix_buffer

It's unused and doesn't need to be initialized

tests: Fix warning about comparison between signed and unsigned

core: Reduce string copies in GetGameFileFromPath()

CMakeLists: disable -Winvalid-offsetof

This Clang warning complains when offsetof is used on a
non-standard-layout type (i.e. any class using various C++ features),
even though it works fine (and is not undefined behavior as of C++17).

core: Eliminate remaining usages of the global system instance

Removes all remaining usages of the global system instance. After this,
migration can begin to migrate to being constructed and managed entirely
by the various frontends.

savedata_factory: Eliminate usage of the global system instance

Now there's only two meaningful instances left in core.

service: Eliminate usages of the global system instance

Completely removes all usages of the global system instance within the
services code by passing in the using system instance to the services.

codec: Fix `pragma GCC diagnostic pop` missing corresponding push

Force early fragment tests when the 3D method is enabled.
The established pipeline cache takes care of recompiling if needed.

This is implemented only on Vulkan to avoid invalidating the shader
cache on OpenGL.

Eliminates some minor string churn where applicable. Also eliminates an
unnecessary vector copy.

nvdrv, video_core: Don't index out of bounds when given invalid syncpoint ID

nvservices: Reintroducee IoctlCtrl

Add an equivalent to 'Common::AlignUp(n, d) / d' and a log2 alternative.

input_common: unbreak -Werror with Clang

error: unknown warning option '-Werror=unused-but-set-parameter'; did you mean '-Werror=unused-parameter'? [-Werror,-Wunknown-warning-option]
error: unknown warning option '-Werror=unused-but-set-variable'; did you mean '-Werror=unused-const-variable'? [-Werror,-Wunknown-warning-option]

Overhaul EmuWindow::PollEvents to fix yuzu-cmd calling SDL_PollEvents off main thread

renderer_vulkan: Implement alpha testing
