Lioncash f1382cf0e7 core: Remove Core::CurrentProcess() 
This only encourages the use of the global system instance (which will
be phased out long-term). Instead, we use the direct system function
call directly to remove the appealing but discouraged short-hand.

Lioncash f763e23083 kernel/vm_manager: Correct doxygen comment parameter tags for MapPhysicalMemory/UnmapPhysicalMemory 
Corrects the parameter names within the doxygen comments so that they
resolve properly.

Lioncash b0da7e4262 kernel/vm_manager: Move variables closer to usage spots in MapPhysicalMemory/UnmapPhysicalMemory 
Narrows the scope of variables down to where they're only necessary.

Lioncash 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.

Lioncash 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.

Lioncash a43ee8d752 kernel/vm_manager: std::move shared_ptr instance in MergeAdjacentVMA 
Avoids an unnecessary atomic reference count increment and decrement.

Lioncash 785c4946dd kernel/vm_manager: Deduplicate iterator creation in MergeAdjacentVMA 
Avoids needing to read the same long sequence of code in both code
paths. Also makes it slightly nicer to read and debug, as the locals
will be able to be shown in the debugger.

Lioncash 70485e690b kernel/vm_manager: Simplify some std::vector constructor calls 
Same behavior, one less magic constant to read.

Lioncash 3f695333cd kernel/vm_manager: Simplify some assertion messages 
Assertions already log out the function name, so there's no need to
manually include the function name in the assertion strings.

Fernando Sahmkow 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.

Fernando Sahmkow 5e457bf258 Kernel: Downgrade WaitForAddress and SignalToAddress messages to Trace. 
This messages were originally set as warnning since few games used these
svcs and it was needed for debugging. This is no longer the case.

Lioncash 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.

Michael Scire 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.
