Convert the various capture* constants in nsIFilePicker into a proper enum, and perform validation when passing it across IPC. Additionally, unlike the previous two enums, reduce the size of CaptureTarget to 8 bits. This is a workaround for its use with nsAttrValue, which at present very specifically requires that parseable enums' values fit within an `int16_t` -- and a `uint16_t` does not.
