ameerj 5fa6b15215 kernel: KScopedReservation implementation
This implements KScopedReservation, allowing resource limit reservations to be more HW accurate, and release upon failure without requiring too many conditionals.

kernel: Unify result codes (#5890)
* kernel: Unify result codes

Drop the usage of ERR_NAME convention in kernel for ResultName. Removed seperation between svc_results.h & errors.h as we mainly include both most of the time anyways.

* oops

* rename errors to svc_results

Lioncash 40ab2b9348 k_address_arbiter: Unfold R_UNLESS macros
Allows for more descriptive error messages and also doesn't hide
control-path exit returns from the reader.

Lioncash b8fc74d74d k_address_arbiter: Remove unnecessary usages of std::addressof
This is a useful function in a generic context or with types that
overload unary operator&. However, primitives and pointers will never do
this, so we can opt for a more straightforward syntax.

Lioncash 7b9c58880f k_address_arbiter: Remove dead code
This code is never used, so we can remove it. It's in version control,
so it can always be brought back when needed.

Lioncash 75a60a6e22 svc: Provide more detailed error logs for svc functions
Allows SVC calls to have much more informative information during error
cases. This also doesn't hide control flow returns from the reader.

Lioncash 756365386a k_affinity_mask: Avoid implicit truncation to bool

Lioncash b944edc85d k_priority_queue: Unfold several declval usages
Given these are only used as function existence checks, we can simplify
some usages of declval, given they aren't particularly useful here.

Reduces a few template instantiations, which at most reduces compile
times a tiny bit.

Lioncash 53aec1fe2d k_priority_queue: Resolved reserved identifier
An identifier containing a starting underscore followed by a capital
letter is reserved by the standard. It's trivial to avoid this by moving
the underscore to the end of the identifier.

While the likelihood of clashing here being minimal, we can turn a
"should not break" scenario into a definitive "will not break" one, so
why not?.

ReinUsesLisp b3587102d1 core/memory: Read and write page table atomically
Squash attributes into the pointer's integer, making them an uintptr_t
pair containing 2 bits at the bottom and then the pointer. These bits
are currently unused thanks to alignment requirements.

Configure Dynarmic to mask out these bits on pointer reads.

While we are at it, remove some unused attributes carried over from
Citra.

Read/Write and other hot functions use a two step unpacking process that
is less readable to stop MSVC from emitting an extra AND instruction in
the hot path:

 mov         rdi,rcx
 shr         rdx,0Ch
 mov         r8,qword ptr [rax+8]
 mov         rax,qword ptr [r8+rdx*8]
 mov         rdx,rax
-and         al,3
 and         rdx,0FFFFFFFFFFFFFFFCh
 je          Core::Memory::Memory::Impl::Read<unsigned char>
 mov         rax,qword ptr [vaddr]

- For `std::same_as`, add missing include of `<concepts>`.

  and use that instead.

  This would also be found in `<concepts>`, but unlike `std::same_as`,
  `std::convertible_to` is not yet implemented in libc++, LLVM's STL
  implementation - not even in master.  (In fact, `std::same_as` is the
  *only* concept currently implemented.  For some reason.)

warning.

The move *constructor* is still defaulted, and is required to exist due

Lioncash da7be67daf ipc_helpers: Remove usage of the global system instance
Resolves numerous deprecation warnings throughout the codebase due to
inclusion of this header. Now building core should be significantly less
noisy (and also relying on less global state).

This also uncovered quite a few modules that were relying on indirect
includes, which have also been fixed.

Lioncash fc6db97a09 core: Remove usage of unicorn
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.

ReinUsesLisp b9a9b83bee kernel: Implement host thread register methods without locking
Locks on GetCurrentHostThreadID were causing performance issues
according to Visual Studio's profiler. It was consuming twice the time
as arm_interface.Run(). The cost was not in the function itself but in
the lockinig it required.

Reimplement these functions using atomics and static storage instead of
an unordered_map. This is a side effect to avoid locking and using linked
lists for reads.

Replace unordered_map with a linear search.
