core_timing: Make usage of nanoseconds more consistent in the interface

alignment: Simplify AlignmentAllocator implementation

filesystem: Create subdirectories prior to creating a file

video_core: Add asynchronous shader decompilation and compilation

vulkan: Make use of designated initializers where applicable

mii/manager: Make use of designated initializers

vk_device: Fix build error on old MSVC versions

mii/manager: Resolve sign mismatch warnings

Designated initializers on old MSVC versions fail to build when they
take the address of a constant.

dmnt_cheat_vm: Implement opcode 0xC3 (ReadWriteStaticRegister)

fs: Fix RomFS building when zero byte files are present

vk_state_tracker: Fix dirty flags for stencil_enable on VK_EXT_extended_dynamic_state

With C++20, much of the allocator interface has been simplified, so we
can make the same adjustments.

macro_hle: Remove unnecessary std::make_pair calls

shader_cache: Make use of std::erase_if

settings: Make use of std::string_view over std::string for logging

core/CMakeLists: Add missing physical_memory.h header file

kernel: Remove unused variables

kernel/thread: Remove unimplemented function prototype

These functions are already in an anonymous namespace which makes the
functions internally linked.

constants: Add missing <array> include

macro: Resolve missing parameter in doxygen comment

macro_hle: Simplify shift expression in HLE_771BB18C62444DA0()

Allows this header file to show up in IDE CMake generators.

Given the expression involves a 32-bit value, this simplifies down to
just: 0x3ffffff. This is likely a remnant from testing that was never
cleaned up.

Resolves a -Wshift-overflow warning.

The purpose of make_pair is generally to deduce the types within the
pair without explicitly specifying the types, so these usages were
generally unnecessary, particularly when the type is enforced by the
array declaration.

Resolves a -Wdocumentation warning.

Eliminates reliance on an indirect include.

Previously the loop termination condition was testing variables of
different signedness.

vk_texture_cache: Amend mismatched access masks and indices in UploadBuffer

Allows returning the structure in a more concise manner.
