synapticsmst: Adjust EVB board handling

1. Since board ID in synapticsmst.quirk is different based upon how
the board ID is read, don't whitelist it in `write_firmware`

2. Allow using `--force` with `fwupdmgr` or `fwupdtool` to override
board ID check.

3. Allow using custom flag `ignore-board-id` to ignore board IDs.
This will be the default for EVB boards and can be used in the event
of a factory mistake as well.

4. Move the EVB board IDs into their own synapticsmst_evb.quirk.
This file will not be installed by default (So EVB boards are only
functional when manually installed).
