uvideo: import quirks infrastructure from OpenBSD

Import the device quirk system from OpenBSD to handle UVC devices
that need special handling. This includes:

• UVIDEO_FLAG_ISIGHT_STREAM_HEADER: non-standard streaming header
• UVIDEO_FLAG_REATTACH: needs reattach after firmware upload
• UVIDEO_FLAG_VENDOR_CLASS: incorrectly reports as vendor class
• UVIDEO_FLAG_NOATTACH: device not supported
• UVIDEO_FLAG_FORMAT_INDEX_IN_BMHINT: format index in bmHint

Add quirks table with known devices and lookup function.
Add iSight stream header decoder for Apple iSight cameras.
