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]
 movzx       eax,byte ptr [rdx+rax]

comex 388cf58b31 k_priority_queue: Fix concepts use 
- For `std::same_as`, add missing include of `<concepts>`.

- For `std::convertible_to`, create a replacement in `common/concepts.h`
  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.)

Lioncash 2de124e223 svc: Remove unnecessary casts 
Simplifies and removes some casts. In all cases, these were generally
widening from a 32-bit unsigned type to a 64-bit unsigned type, so no

comex e31cb50405 Fix "explicitly defaulted but implicitly deleted" warning 
`PhysicalCore`'s move assignment operator was declared as `= default`,
but was implicitly deleted because `PhysicalCore` has fields
of reference type.  Switch to explicitly deleting it to avoid a Clang
warning.

The move *constructor* is still defaulted, and is required to exist due
to the use of `std::vector<PhysicalCore>`.

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

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

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.

This also updates httplib to 0.7.9, as there are several warning
cleanups made that allow us to enable several warnings as errors.

ReinUsesLisp ccdd84a778 hle/scheduler: Fix data race in is_context_switch_pending 
As reported by tsan, SelectThreads could write to
is_context_switch_pending holding a mutex while SwitchToCurrent reads it
without holding any.

It is assumed that the author didn't want an atomic here, so the code is
reordered so that whenever is_context_switch_pending is read inside
SwitchToContext, the mutex is locked.
