I forgot to remove this in the rebase when removing most of the global
variables within the input common codebase.

input_common: Eliminate most global state

cpu_interrupt_handler: Make is_interrupted an atomic

Abstracts most of the input mechanisms under an InputSubsystem class
that is managed by the frontends, eliminating any static constructors
and destructors. This gets rid of global accessor functions and also
allows the frontends to have a more fine-grained control over the
lifecycle of the input subsystem.

This also makes it explicit which interfaces rely on the input subsystem
instead of making it opaque in the interface functions. All that remains
to migrate over is the factories, which can be done in a separate
change.

Project Mjölnir: Part 1 - Input Rewrite

common/assert: Make use of C++ attribute syntax

shader/memory: Amend UNIMPLEMENTED_IF_MSG without a message

video_core/host_shaders: Add CMake integration for string shaders

vk_state_tracker: Fix primitive topology

memory_manager: Make operator+ const qualified

This doesn't modify member state, so it can be marked as const.

Supports the Left, Right, Middle, Backward and Forward mouse buttons.

This allows homebrew applications to be able to properly detect connected controllers.

The hardware tested value is 0.5 which translates to SHRT_MAX / 2

Fixes a race condition detected from tsan

externals: Update Xbyak to 5.95

5.95 contains a potentially backward-compatibility breaking change, so
we should be updating to this to ensure that our code remains
forward-compatible.

externals: Update xbyak to v5.941

memory_manager: Mark IsGranularRange() as a const member function

microprofile: Don't memset through std::atomic types

registered_cache: Make use of designated initializers

common/color: Migrate code over to the Common namespace

video_core: Initialize renderer with a GPU

cpu_manager: Make use of ranged for where applicable

Normalizes the syntax used for attributes

gl_texture_cache: Take std::string by reference in DecorateViewName()

This doesn't modify internal member state, so it can be marked as const.

LabelGLObject takes a string_view, so we don't need to make copies of
the std::string.

video_core/fence_manager: Remove unnecessary includes

Keeps the tracked submodule up to date with the latest release.

Avoids pulling in unnecessary things that can cause rebuilds when they
aren't required.
