The name that the Raw Input joystick driver pulls from the HID stack comes
from USB string descriptors contained on the device. For official wireless
receivers, this always contains "Xbox 360 Wireless Receiver for Windows"
which matches the friendly name that WGI provides.
3rd party Xbox 360 wireless receivers may have different strings in their
USB string descriptors (one uses "XBOX 360 For Windows" instead). This
fails to match WGI's name and causes Raw Input and WGI to both report the
same gamepad.
Since wireless Xbox 360 controllers seem to have a consistent VID/PID
regardless of the adapter enumerating them, we can also match on that to
catch these.
The duplicate case reported to me was:
Controller (XBOX 360 For Windows) - 030000005e040000a102000000007200
Xbox 360 Wireless Receiver for Windows - 030000005e0400000000000000007701
We can also ditch the lock in RAWINPUT_JoystickQuit() now that the joystick
subsystem quits drivers in reverse order. There's no chance of a racing call
to RAWINPUT_WindowProc() anymore.
i.e. where the string is known guaranteed to be WCHAR*, in:
- SDL_dinputjoystick.c (WIN_IsXInputDevice): VARIANT->var is BSTR (WCHAR*)
- SDL_rawinputjoystick.c (RAWINPUT_AddDevice): string is WCHAR*
- SDL_windows_gaming_input.c (IEventHandler_CRawGameControllerVtbl_InvokeAdded):
string is WCHAR*
There should be more of these..

Eliminate additional heap allocation for short-lived HSTRINGs.
Uses `WindowsCreateStringReference()` to disable reference counting and memory management by the Window Runtime.

Currently the rawinput driver always reports a device as "wired". This changes that to "unknown" and updates it once the device is correlated with xinput.
Most of the raw input events are dispatched in the main windows message loop. We only dispatch device change messages separately when we need them to be completely up to date.
src/joystick/windows/SDL_rawinputjoystick.c: In function 'RAWINPUT_HandleStatePacket':
src/joystick/windows/SDL_rawinputjoystick.c:1343:9: warning: suggest explicit braces to avoid ambiguous 'else'
This fixes bad report parsing for various newer Xbox controllers, and this driver is now preferred over XInput, since it handles more than 4 controllers.
Added support for the PS4 controller gyro and accelerometer on iOS and HIDAPI drivers
Also fixed an issue with the accelerometer on iOS having inverted axes
