96cc9a9279 kernel/vm_manager: Correct behavior in failure case of UnmapPhysicalMemory()
If an unmapping operation fails, we shouldn't be decrementing the amount
of memory mapped and returning that the operation was successful. We
should actually be returning the error code in this case.

56c6f767ae kernel/vm_manager: Reserve memory ahead of time for slow path in MergeAdjacentVMA
Avoids potentially expensive (depending on the size of the memory block)
allocations by reserving the necessary memory before performing both
insertions. This avoids scenarios where the second insert may cause a
reallocation to occur.

785c4946dd kernel/vm_manager: Deduplicate iterator creation in MergeAdjacentVMA
Avoids needing to read the same long sequence of code in both code

9bede4eeed VM_Manager: Align allocated memory to 256bytes
This commit ensures that all backing memory allocated for the Guest CPU
is aligned to 256 bytes. This due to how gpu memory works and the heavy
constraints it has in the alignment of physical memory.

16730c4c43 service/audren_u: Handle audio USB output revision queries in ListAudioDeviceName()
Audio devices use the supplied revision information in order to
determine if USB audio output is able to be supported. In this case, we
can only really handle using this revision information in
ListAudioDeviceName(), where it checks if USB audio output is supported
before supplying it as a device name.

A few other scenarios exist where the revision info is checked, such as:

- Early exiting from SetAudioDeviceOutputVolume if USB audio is
  attempted to be set when that device is unsupported.

- Early exiting and returning 0.0f in GetAudioDeviceOutputVolume when
  USB output volume is queried and it's an unsupported device.

- Falling back to AHUB headphones in GetActiveAudioDeviceName when the
  device type is USB output, but is unsupported based off the revision
  info.

In order for these changes to also be implemented, a few other changes
to the interface need to be made.

Given we now properly handle everything about ListAudioDeviceName(), we
no longer need to describe it as a stubbed function.

AudioDevice and AudioInterface aren't valid device names on the Switch.

ListAudioDeviceName, by returning all the available devices on the
Switch.

70624e1c1d core/arm: Remove obsolete Unicorn memory mapping
This was initially necessary when AArch64 JIT emulation was in its
infancy and all memory-related instructions weren't implemented.

Given the JIT now has all of these facilities implemented, we can remove
these functions from the CPU interface.

072a9796f5 Restore memory perms on svcUnmapMemory/UnloadNro
Prior to PR, Yuzu did not restore memory to RW-
on unmap of mirrored memory or unloading of NRO.

(In fact, in the NRO case, the memory was unmapped
instead of reprotected to --- on Load, so it was
actually lost entirely...)

This PR addresses that, and restores memory to RW-
as it should.

This fixes a crash in Super Smash Bros when creating
a World of Light save for the first time, and possibly
other games/circumstances.

697206092e Prevent merging of device mapped memory blocks.
This sets the DeviceMapped attribute for GPU-mapped memory blocks,
and prevents merging device mapped blocks. This prevents memory
mapped from the gpu from having its backing address changed by
block coalesce.

13a8fde3ad Implement MapPhysicalMemory/UnmapPhysicalMemory
This implements svcMapPhysicalMemory/svcUnmapPhysicalMemory for Yuzu,
which can be used to map memory at a desired address by games since
3.0.0.

It also properly parses SystemResourceSize from NPDM, and makes
information available via svcGetInfo.

This is needed for games like Super Smash Bros. and Diablo 3 -- this
PR's implementation does not run into the "ASCII reads" issue mentioned
in the comments of #2626, which was caused by the following bugs in
Yuzu's memory management that this PR also addresses:
* Yuzu's memory coalescing does not properly merge blocks. This results
  in a polluted address space/svcQueryMemory results that would be
  impossible to replicate on hardware, which can lead to game code making
  the wrong assumptions about memory layout.
  * This implements better merging for AllocatedMemoryBlocks.
* Yuzu's implementation of svcMirrorMemory unprotected the entire
  virtual memory range containing the range being mirrored. This could
  lead to games attempting to map data at that unprotected
  range/attempting to access that range after yuzu improperly unmapped
  it.
  * This PR fixes it by simply calling ReprotectRange instead of
    Reprotect.

56c7912159 kernel/process: Allocate the process' TLS region during initialization
Prior to execution within a process beginning, the process establishes
its own TLS region for uses (as far as I can tell) related to exception
handling.

Now that TLS creation was decoupled from threads themselves, we can add
this behavior to our Process class. This is also good, as it allows us
to remove a stub within svcGetInfo, namely querying the address of that
region.
