Unicorn long-since lost most of its use, due to dynarmic gaining support
for handling most instructions. At this point any further issues
encountered should be used to make dynarmic better.

This also allows us to remove our dependency on Python.

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.

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

* 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.

It's deprecated in the language to autogenerate these if the destructor
for a type is specified, so we can explicitly specify how we want these
to be generated.

Prevents values from mistakenly being discarded in cases where it's a
bug to do so.

The API of VP9 exposes a WasFrameHidden() function which accesses this
member. Given the constructor previously didn't initialize this member,
it's a potential vector for an uninitialized read.

Instead, we can initialize this to a deterministic value to prevent that
from occurring.

These helper functions don't directly modify any member state and can be
hidden from view.

externals: Update fmt to 7.1.0

nvdec: Minor tidying up

Adds 1 async worker thread for every 2 available threads above 8

Add hotplug, rumble and fix 3rd party adapters for the GC adapter

kernel/process: Add missing <ctime> include

Fixes compilation on MSVC

web_service: follow-up fix to #4842

kernel: Use the current time as the default RNG seed

sync_manager: Amend parameter order of calls to SyncptIncr constructor

* The web_service http request is now fixed on Windows (R) platform.
* The issue is due to a complicated race-condition in `httplib`, a detailed
  explanation is available at https://github.com/yhirose/cpp-httplib/pull/701
* A pending Pull Request on `httplib` has been applied to remedy the
  said race-condition.
* The socket availability check is removed due to a behavioral chice of
  `httplib` that a socket will not be created before any actual request
  is sent.

web_service: web_backend: Handle socket errors with GenericRequest.

- Fixes a shutdown crash when we try to submit telemetry if there is a service issue.

video_core: cdma_pusher: Add missing LOG_DEBUG field in ExecuteCommand.

service: Update function tables

Trivially add the encoding for this.

externals: Track upstream inih
