libcamera: controls: Move ControlValue constructor to controls.h
To avoid defining all specializations of the ControlValue constructor manually, move the definition of those functions to controls.h and turn them into a single template function. The default constructor is still kept in controls.cpp. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
