cpu_detect: Refactor detection of processor features

Set the zero-enum value to Unknown
Move the Manufacterer enum into the CPUCaps structure namespace
Add "ParseManufacturer" utility-function
Fix cpu/brand string buffer sizes(!)

Update some uses of `int` into some more explicitly sized types as well

As this structure gets more explicit, bools can be bitfields and
small enums can use smaller types for their span of values.

Extracts a singular bit, as a bool, from the specified compile-time index.

hle: service: ldr: Use deterministic addresses when mapping NROs.

- Instead of randomization, choose in-order addresses for where to map NROs into memory.
- This results in predictable behavior when debugging and consistent behavior when reproducing issues.

core, video_core: Fix two crashes when failing to create the emulated GPU instance

shader_recompiler/LOP3: Use brute force python results within switch/case.

Thanks to @asLody for optimizing this function. This raised the focus that this function should be optimized more.

The current table assumes that the host GPU is able to invert for free, so only AND,OR,XOR are accumulated in the performance metrik.

Performance results:

Instructions
0: 8
1: 30
2: 114
3: 80
4: 24

Latency
0: 8
1: 30
2: 194
3: 24

Kernel Memory Updates (Part 5): Revamp MapCodeMemory and UnmapCodeMemory.

- This makes these functions more accurate to the real HOS implementations.
- Fixes memory access issues in Super Smash Bros. Ultimate that occur when un/mapping NROs.

When CreateRenderer fails, the GraphicsContext that was std::move'd into
it is destroyed before the Scoped that was created to manage its
currency. In that case, the GraphicsContext::Scoped will still call its
destructor at the ending of the function. And because the context is
destroyed, the Scoped will cause a crash as it attempts to call a
destroyed object's DoneCurrent function.

Since we know when the call would be invalid, call the Scoped's Cancel
method. This prevents it from calling a method on a destroyed object.

If a GraphicsContext is destroyed before its Scoped is destroyed, this
causes a crash as the Scoped tries to call a method in the destroyed
context on exit.

Add a way to Cancel the call when we know that calling the
GraphicsContext will not work.

MaxwellDMA: Implement semaphore operations

When CreateGPU fails, yuzu would try and shutdown the GPU instance
regardless of whether any instance was actually created.

Check for nullptr before calling its methods to prevent a crash.

* gl_graphics_pipeline: Improve shader builder synchronization

Make use of GLsync objects to ensure better synchronization between shader builder threads and the main context

* gl_graphics_pipeline: Make built_fence access threadsafe

* gl_graphics_pipeline: Use GLsync objects only when building in parallel

* gl_graphics_pipeline: Replace GetSync calls with non-blocking waits

The spec states that a ClientWait on a Fence object ensures the changes propagate to the calling context

host_memory: Fix fastmem crashes in debug builds

logging: Convert `backend_thread` into an `std::jthread`

Kernel Memory Updates (Part 4): Revamp KMemoryManager & other fixes

It is possible for virtual_offset to not be 0 when the iterator is at the beginning, and thus, std::prev(it) may be evaluated, leading to a crash in debug mode.

dynarmic: Inline exclusive memory accesses

Update translations (2022-03-01)

gl_fence_manager: Minor optimization to signal querying

ffmpeg: Fix mis-maching argument warning for endif

- As this can only be derived once.

- Updates the KMemoryManager implementation against latest documentation.
- Reworks KMemoryLayout to be accessed throughout the kernel.
- Fixes an issue with pool sizes being incorrectly reported.

Was getting an unhandled `invalid_argument` [exception](https://en.cppreference.com/w/cpp/thread/thread/join) during
shutdown on my linux machine. This removes the need for a `StopBackendThread` function entirely since `jthread`
[automatically handles both checking if the thread is joinable and stopping the token before attempting to join](https://en.cppreference.com/w/cpp/thread/jthread/~jthread) in the case that `StartBackendThread` was never called.

Per the spec, bufSize is the number of integers that will be written, in this case, 1.

Also, the length argument is optional if the information of the number of elements written is not needed.

Inlines implementation of exclusive instructions into JITted code,
improving performance of applications relying heavily on these
instructions.

We also fastmem these instructions for additional speed, with
support for appropriate recompilation on fastmem failure.

An unsafe optimization to disable the intercore global_monitor is also
provided, should one wish to rely solely on cmpxchg semantics for
safety.
