This makes a lot more sense; we can parse a firmware and export the same XML
we would use in a .builder.xml file. This allows us to two two things:
* Check we can round trip from XML -> binary -> XML
* Using a .builder.xml file we can check ->write() is endian safe
This allows us to 'nest' firmware formats, and removes a ton of duplication.
The aim here is to deprecate FuFirmwareImage -- it's almost always acting
as a 'child' FuFirmware instance, and even copies most of the vfuncs to allow
custom types. If I'm struggling to work out what should be a FuFirmware and
what should be a FuFirmwareImage then a plugin author has no hope.
For simple payloads we were adding bytes into an image and then the image into
a firmware. This gets really messy when most plugins are treating the FuFirmware
*as* the binary firmware file.
The GBytes saved in the FuFirmware would be considered the payload with the
aim of not using FuFirmwareImage in the single-image case.
These are expected to be flashed via UEFI capsules *not* Thunderbolt plugin
* Flashing via fwupd will require matching kernel work.
* They're left here only for parsing the binaries

Thunderbolt images brought in from the SPI don't have a FARB header.
Thunderbolt update images do.
So these two types of images need to be handled separately from the
firmware parser.
Remove it's references to it's own GUdevclient and instead use
FuUdevDevice.
Some intentional casualties of the move:
* Plugin metadata around native and safe mode dropped.
- These haven't been useful in debugging anything and aren't relevant
on new hardware
* Extra GUID for 2 host controllers in same system dropped
- Although this was normally static information BIOS operations like
turning off PCI-E SD card reader or LAN controller changed things.
* The NVM version is parsed directly instead of through gudev to prevent
cached data breaking change events.
Remaining TODO:
* Force power w/ thunderbolt-power doesn't work
