Gamepad rumble support with SDL2 (#3819)

* Added gamepad rumble to rcore_desktop.c and rcore_desktop_sdl.c
Still need to add to the rest of the platforms.

* Add SetGamepadVibration warnings to unimplemented platforms.

* Added MAX_GAMEPAD_VIBRATION_TIME
The rumble in SDL2 will continue for MAX_GAMEPAD_VIBRATION_TIME unless the user cancels it with a call to SetGamepadVibration(0.0f,0.0f,0.0f)

* Cast float duration value to Uint 32

* Changed defines from int to float and fixed typo
