libcamera: Extend u32 control type

Browse Source 
V4L2 Controls support a wide variety of types not yet supported by the
ControlValue type system.

Extend the libcamera ControlValue types to support an explicit 32 bit
unsigned integer type, and map that to the corresponding
V4L2_CTRL_TYPE_U32 type within the v4l2_device support class.
