SharedMemory: Don't take over and unmap the source memory block when creating a shared memory, just reference it

macOS: Build x86_64h slice

Kernel/SharedMemory: Don't take over and unmap the source memory block when creating a shared memory, just reference it.

Also reference the right offset into the backing block for the requested address.

This commit produces a fat-binary with two slices. The x86_64 slice
is for all x64 systems, and the x86_64h slice targets x64 systems
starting with Haswell. The latter allows the compiler to use newer
instructions that are not available on older microarchitectures.

Memory: Add overloads for ReadBlock and WriteBlock that operate on a specific process.

Services/NIM: Implement CheckForSysUpdateEvent.

Moved down_count to CoreTiming

Implementation verified by reverse engineering.
This lets the Home Menu boot without crashing on startup.

Services/UDS: Handle the rest of the connection sequence.

Add the .vs folder and the CMakeSettings.json file from Visual Studio to gitignore

Implement PrepareToStartNewestHomeMenu and fixed an APT regression.

Kernel/Threads: When putting a thread to wait, specify a function to execute when it is awoken

Fixed type conversion ambiguity

Loaders: Don't automatically set the current process every time we load an application.

This change makes for a clearer (less confusing) path of execution in the scheduler, now the code to execute when a thread awakes is closer to the code that puts the thread to sleep (WaitSynch1, WaitSynchN). It also allows us to implement the special wake up behavior of ReplyAndReceive without hacking up WaitObject::WakeupAllWaitingThreads.

If savestates are desired in the future, we can change this implementation to one similar to the CoreTiming event system, where we first register the callback functions at startup and assign their identifiers to the Thread callback variable instead of directly assigning a lambda to the wake up callback variable.

Disable unary operator- on Math::Vec2/Vec3/Vec4 for unsigned types.

It is unlikely we will ever use this without first doing a Cast to a signed type.
Fixes 9 "unary minus operator applied to unsigned type, result still unsigned" warnings on MSVC2017.3

The loaders will now just create a Kernel::Process, construct it and return it to the caller, which is responsible for setting it as the current process and configuring the global page table.

Memory/RasterizerCache: Ignore unmapped memory regions when caching physical regions

Don't automatically assume that Thread::Create will only be called when the parent process is currently scheduled. This assumption will be broken when applets or system modules are loaded.

There is still an overload of IsValidVirtualAddress that only takes the VAddr and will default to the current process.

Audio: Use std::deque instead of std::vector for the audio buffer type (StereoBuffer16)

Not all physical regions need to be mapped into the address space of every process, for example, system modules do not have a VRAM mapping.

This fixes a crash when loading applets and system modules.

The current code inserts and deletes elements from the beginning of the audio buffer, which is very inefficient in an std::vector.

Profiling was done using VisualStudio2017's Performance Analyzer in Super Mario 3D Land.

Before this change: AudioInterp::Linear had 14.14% of the runtime (inclusive) and most of that time was spent in std::vector's insert implementation.
After this change: AudioInterp::Linear has 0.36% of the runtime (inclusive)

HLE/Archives: Allow multiple loaded applications to access their SelfNCCH archive independently.

The loaders now register each loaded ROM with the SelfNCCH factory, which keeps the data around for the duration of the emulation session.

When opening the SelfNCCH archive, the factory queries the current program's programid and uses that as a key to the map that contains the NCCHData structure (RomFS, Icon, Banner, etc).

3dsx files do not have a programid and will use a default of 0 for this value, thus, only 1 3dsx file with RomFS is loadable at the same time.

Switchable Page Tables
