kernel: Remove unused variables

vfs_vector: Make creation of array vfs files less verbose

game_list_worker: Do not clear entries when > 1 gamedir is present

am: Unstub SetScreenShotPermission

video_core: Remove redundant pixel format type

ci: Make use of clang-format 10.0

common/concepts: Rename IsBaseOf to DerivedFrom

This makes it more inline with its currently unavailable standardized
analogue std::derived_from.

While we're at it, we can also make the template match the requirements
of the standardized variant as well.

partition_data_manager: Make data arrays constexpr

address_arbiter/scheduler: Resolve sign conversion warnings

Fills in some hashes that were previously unhandled.

Previously the constructor for all of these would run at program
startup, consuming time before the application can enter main().

This is also particularly dangerous, given the logging system wouldn't
have been initialized properly yet, yet the program would use the logs
to signify an error.

To rectify this, we can replace the literals with constexpr functions
that perform the conversion at compile-time, completely eliminating the
runtime cost of initializing these arrays.

ipc_helpers: Only allow trivially copyable objects with PushRaw() and PopRaw()

aes_util: Allow SetIV() to be non-allocating

logging/backend: Make use of designated initializers

buffer_queue: Make use of designated initializers/std::nullopt where applicable

CMakeLists: Resolve #4478

Resolves a few compiler warnings.

Makes our type conversion explicit.

common/atomic_ops: Don't cast away volatile from pointers

It's undefined behavior to use non-trivially copyable objects with
std::memcpy, so we can add asserts to catch usages of these at
compile-time.

We can add a helper function to make creation of these files nicer.
While we're at it, we can eliminate an unnecessary std::array copy in
the constructor. This makes the overhead on some of these functions way
less intensive, given some arrays were quite large.

e.g. The timezone location names are 9633 bytes in size.

loader: Make IdentifyFile typesafe

Previously the map of entries was being cleared while looping through each game directory, this resulted into all game directories except the last game dir to lose content metadata information. Fix this by clearing the entries only once.

time_zone_binary: Make use of designated initializers

vi: IApplicationDisplayService:GetIndirectLayerImageRequiredMemoryInfo

hle: nvdrv: Rewrite of GPU memory management.

CMakeLists: Update several libraries

renderer_opengl: Use 1/4 of all threads for async shader compilation

game_list_worker: Fix game list subdirectory scanning

perf_stats: Mark GetMeanFrametime() as const 

vk_texture_cache: Silence -Wmissing-field-initializer warnings

patch_manager: Resolve -Wignored-qualifier warnings

yuzu: Resolve C++20 deprecation warnings related to lambda captures

profile_manager: Make use of designated initializers 

dmnt_cheat_vm: Make use of designated initializers

fsp-srv: Stub Read/WriteSaveDataFileSystemExtraDataWithMaskBySaveDataAttribute

In a few places, the data to be set as the IV is already within an array.
We shouldn't require this data to be heap-allocated if it doesn't need
to be. This allows certain callers to reduce heap churn.
