[webhid] Add missing report item bitfield attributes

The Device Class Definition for HID defines a bitfield that
accompanies each Main item in the HID report descriptor. The
bitfield is a 32-bit value that defines 9 attributes. Three
of these attributes were already exposed in the HID report
item dictionary (isAbsolute, isArray, hasNull), this CL adds
the remaining six.
