Emscripten was using its own, private integer in order to allocate
new SDL_JoystickIDs. SDL keeps a similar integer for allocating
joystick-ids, one which is shared across multiple joystick backends.
SDL 2.0.13 introduces a new joystick-backend, a Virtual joystick
backend, which allows for software-driven joysticks, and which is
designed to sit alongside joystick-backends that provide access to
physical joysticks.
The Emscripten and the Virtual backends were, at times, getting
allocated the same SDL_JoystickIDs, if and when both backends were used
simultaneously. This could happen if, for example, an application
was using a virtual joystick in order to drive a touch-screen
based joystick, while also supporting physical joysticks through the
Emscripten backend.
When two joysticks end up with the same SDL_JoystickID, conflicts
can occur. For example, disconnecting a physical joystick with
the same SDL_JoystickID as a virtual one, can lead to the virtual
joystick being closed, inadvertently.
This fix makes the Emscripten backend use SDL's cross-joystick-backend
integer counter, which is shared among joystick backends, for allocating
new SDL_JoystickIDs, rather than a private, Emscripten-specific
counter.

This reverts commit e5a15f94e2.
It turns out removing this check allows mice like the ROG PUGIO II to show up as game controllers. We need to find a different way to differentiate between gaming mice and pedals.
Since these mice show up as controllers, and potentially causing games to use them instead of real controllers, we'll go ahead revert this change for now.

HIDAPI joystick drivers may call HIDAPI_JoystickDisconnected() in their
UpdateDevice() function during HIDAPI_JoystickOpen(). If they do this
today, the opened joystick will end up partially initialized (no name,
path, mapping GUID, etc.) because HIDAPI_GetDeviceByIndex() will no
longer be able to find the SDL_HIDAPI_Device for the removed joystick.
Worse still, joystick->hwdata->device becomes a dangling freed pointer
the next time HIDAPI_UpdateDeviceList() is called. This leads to a UAF
when the application or SDL calls SDL_JoystickClose() on this joystick.
Fix all this by checking if the device no longer has any associated
joysticks after calling UpdateDevice() and failing the open call if so.

Logitech PRO Racing Wheel have two different versions - for Playstation and Xbox. Vendor + Product ID for Playstation version already present in SDL sources, but not an Xbox version

Many of the Flydigi controllers use the same VID/PID and have different mappings, so let's revisit this once we have more data.
(cherry picked from commit 5388edd549)
This adds support for the back paddles, and the "..." key
which are not automatically detected.
* "Back" is mapped to the top left "two windows" key.
* "Start" is mapped to the top right "hambuger menu" key.
* "Guide" is mapped to the "Steam" key.
* The "..." key is just a generic button.
When looking at the screen, paddles are number
* P1: Top right
* P2: Top left
* P3: Bottom right
* P4: Botom Left
The new controller mapping was created with the SDL3 gamepadmap tool.

In this case we know the controller has been on for a while and the Bluetooth connection LED cycle is complete.
Also fixed the timestamp being zero the first time it is checked

If there is only one controller slot available, assume that's the one matching new RAWINPUt devices. This will be right most of the time, and uncorrelation will fix any bad guesses.

The xpad kernel driver doesn't know about these controllers and ends up using BTN_C and BTN_Z and the automatic mapping doesn't work correctly.
It turns out VID 0x045e and PID 0x02e0 is used by the 8BitDo SN30 Pro when connecting via Bluetooth in XInput mode.

Initializing "Windows.Gaming.Input.Gamepad" will put Bluetooth PS4 controllers into enhanced report mode, which breaks any game using DirectInput. Let's wait to do this until absolutely necessary.
