UpdateDevice() can be called at an arbitrary rate, so we need to
pace ourselves to avoid filling up the rumble queue with these.

Add a loop around SDL_hid_read() in the Steam Deck HIDAPI driver as it
is done in other HIDAPI drivers. This loop reads data from the device and
processes it until the input buffer is empty which ensures that clients
always get the latest data.
This fixes an input latency issue if the application polls the events
slower than the hardware generates them.
When they are in simple report mode, the thumbstick gets turned into a digital hat, so let's use them in full report mode.

This breaks applications using them in DirectInput mode, which isn't worth just getting battery status. We'll turn on enhanced mode if the application enables sensors.

On Android, HIDAPI prompts for permissions and acquires exclusive access to the device, and on Apple mobile platforms it doesn't do anything except for handling Bluetooth Steam Controllers.

(cherry picked from commit e3cf2e4794)
Added support for getting the real controller info, as well as the function SDL_GameControllerGetSteamHandle() to get the Steam Input API handle, from the virtual gamepads provided by Steam.
Also added an event SDL_CONTROLLERSTEAMHANDLEUPDATED which is triggered when a controller's API handle changes, e.g. the controllers were reassigned slots in the Steam UI.
(cherry picked from commit c981a597dc)
The 8BitDo Zero 2 only sends reports when state changes, so trips the disconnected Bluetooth controller detection. The expected use case is that most people will have official PS4 controllers in enhanced report mode, so disconnected Bluetooth controller detection will still work for those.

(cherry picked from commit 75df4cc5c2)
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.
(cherry picked from commit 435e7ce663)
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
