common/fiber: Move all member variables into impl class

Hides all of the implementation details for users of the class. This has
the benefit of reducing includes and also making the fiber classes
movable again.

General: Fix clang build

settings: Simplify initializer of resolution factor

This can use a braced initializer to accomplish the same thing with less
code.

shader: Partially implement texture cube array shadow

Allows building on clang to work again

core/settings: Move configuring_global behind an API

General: Resolve a few missing initializer warnings

Rather than have directly modified global state here, we can make it an
implementation detail and have an interface that changes are queried
through.

Improvements to GPU synchronization & various refactoring

nvdec: Make use of [[nodiscard]] where applicable

microprofile: Silence warning in headers

Silences a truncation warning by making the truncation explicit and
documenting the reason for it.

common: Enable warnings as errors

hle: service: ldr: Implement UnloadNrr.

Cleans up common so that we can enable warnings as errors.

Prevents bugs from occurring where the results of a function are
accidentally discarded

async_shaders: Increase Async worker thread count for >8 thread cpus

- Refactor so that SubmitGPFIFO and KickoffPB use shared functionality.
- Implement add_wait and add_increment flags.

- Log corrupted command lists, rather than crash.

* Rename to align with switchbrew

* Rename to align with switchbrew and remove gpu function that checks if clearing should be done.

shader/arithmetic: Implement FCMP immediate + register variant

- Used by Final Fantasy X/X-2 HD Remaster.

video_core: unbreak -Werror in NVDEC with Clang

Prevents the compiler tripping up about Windows headers.

src/core/hle/service/nvdrv/devices/nvhost_nvdec_common.cpp:41:15: error: unused variable 'OutOfMemory' [-Werror,-Wunused-const-variable]
constexpr u32 OutOfMemory{static_cast<u32>(-12)};
              ^

General: Make ignoring a discarded return value an error

VP9: Minor interface changes and safety improvements

MSVC lets us fine-tune catching expressions with no side-effects a
little more.

Allows our CI to catch more potential bugs. This also removes the
[[nodiscard]] attribute of IOFile's Open member function. There are
cases where a file may want to be opened, but have the status of it
checked at a later time.
