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

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.

Two of the members of the MicroProfileThreadLog contains two std::atomic
instances. Given these aren't trivially-copyable types, we shouldn't be
memsetting the structure, given implementation details can contain other
members within it.

To avoid potential undefined behavior on platforms, we can use aggregate
initialization to zero out the members while still having well-defined
behavior.

While we're at it we can also silence some sign conversion warnings.

key_manager: Make data arrays constexpr

Add the necessary CMake code to copy the contents in a string source
shader (GLSL or GLASM) to a header file then consumed by video_core
files.

This allows editting GLSL in its own files without having to maintain
them in source files.

For now, only OpenGL presentation shaders are moved, but we can add
GLASM presentation shaders and static SPIR-V generation through
glslangValidator in the future.

This allows us passing any type of string and hinting the length of the
string to the OpenGL driver.

vfs_real: Avoid redundant map lookups

web_service: Move web_result.h into web_service
