Although they normally work, some failures have been reported in the field
related to the MST hub not responding in the MST plugin.
When these failures have occurred the dell_dock plugin also fails to
enumerate.
So rather than allow some people who don't have dell_dock compiled to
update their MST hub using synaptics_mst, perform ALL updates for
mst hub via dell_dock.

```
This flag is used internally by plugins to indicate that they will
skip the phase of firmware installation that power cycles a device.
It is intended to be set by quirks or other environment settings.
Sometimes we only want to add the instance ID to get the quirk matches, and it
is confusing to see the "fake" IDs in the 'fwupdmgr get-devices' output.
If we say that the version format should be the same for the `version_lowest`
and the `version_bootloader` then it does not always make sense to set it at
the same time.
Moving the `version_format` to a standalone first-class property also means it
can be typically be set in the custom device `_init()` function, which means we
don't need to worry about *changing* ther version format as set by the USB and
UDev superclass helpers.
Synaptics versions are encoded as BCD, the largest version that will
ever be represented in this field is '99'.
Using 3 digits in this field has caused multiple problems in upgrades from
LVFS.
1. Devices are being upgraded when not necessary.
IE `5.3.10 > 5.3.010`
2. Device upgrades are deemed failures as follows:

```
No need to fail these self tests when using amdgpu, just skip them.
