Add bus_type param to GetGamepadStandardMappingFunction

The Standard Gamepad spec lays out a standard configuration for gamepad
buttons and axes. The browser attempts to remap the buttons and axes
reported by connected devices to more closely match the standard. In
most cases, a suitable mapping function can be chosen from the vendor
and product IDs reported by the device.

In some cases this is not sufficient; for instance, some devices are
supported over both USB and Bluetooth and require different mapping
functions in either case. To help select a mapping function in these
cases, a |bus_type| parameter is added to
GetGamepadStandardMappingFunction to specify whether the device is
connected over USB or Bluetooth.
