Fix compilation on macOS

Fix compilation when not building with boxcat

macro_jit_x64: Inline Engines::Maxwell3D::GetRegisterValue

Remove redundant moves

Fixes compilation when trying to build without boxcat enabled

audren: Implement RendererInfo

macro_jit_x64: Optimization correctness

maxwell_to_gl/vk: Miscellaneous changes

arm_dynarmic_32: Fix implicit conversion error in SetTPIDR_EL0

On MSVC builds we treat conversion warnings as errors.

OpenGL macOS headers definitions clash heavily with each other

* boost::hash_value returns a size_t
* boost::hash_combine takes a size_t& argument

macOS header files #define PAGE_SHIFT

Emulate GL_LINEAR/NEAREST minification filters using minLod = 0 and maxLod = 0.25 during sampler creation

maxwell_to_vk: Reorder filtering modes to start with None, then Nearest, then Linear.
maxwell_to_vk: Logs filter modes under UNREACHABLE_MSG instead of UNIMPLEMENTED_MSG, since any unknown filter modes are invalid and not unimplemented.
maxwell_to_vk: Return VK_SAMPLER_MIPMAP_MODE_NEAREST instead of VK_SAMPLER_MIPMAP_MODE_LINEAR when mipmap_filter is None with the description from the VkSamplerCreateInfo(3) man page.

maxwell_to_gl: Log unimplemented features under UNIMPLEMENTED_MSG instead of LOG_ERROR to bring into parity with maxwell_to_vk
maxwell_to_gl: Deduplicate logging in VertexType(), merging them into one.

maxwell_to_gl: Return GL_NEAREST instead of GL_LINEAR if an unknown texture filter mode is encountered.
maxwell_to_gl: Log the mipmap filter mode if an unknown value is passed in.
maxwell_to_gl: Reorder filtering modes to start with None, then Nearest, then Linear.

gl_device: Reserve 4 image bindings for fragment stage

arm_dynarmic: CP15 changes

xbyak_abi: Cleanup

The code generated for these ALU ops assume src_a and src_b are always valid.

macro_jit_x64: Cleanup

qt_themes: remove unknown qss property from dark theme

* externals: Revert to libressl, as build is broken with find_package(OpenSLL).

* fixup! externals: Revert to libressl, as build is broken with find_package(OpenSLL).

gl_arb_decompiler: Implement an assembly shader decompiler

yuzu/frontend: Remove internal resolution option

Due to the limitation of GL_MAX_IMAGE_UNITS being low (8) on Intel's and Nvidia's proprietary drivers, we have to reserve an appropriate amount of image bindings for each of the stages. So far games have been observed to use 4 image bindings on the fragment stage (Kirby Star Allies) and 1 on the vertex stage (TWD series).
No games thus far in my limited testing used more than 4 images concurrently and across all currently active programs.
This fixes shader compilation errors on Kirby Star Allies on OpenGL (GLSL/GLASM)
