The connectivity routine would consider symbols, overwriting unused
subgraphs for pins that were not in the change list. This is resolved
by updating the full connectivity to only use pins in the graph since
symbols are not connected independently.
In the process of adding QA tests for this change, additional issues
with the schematic QA were discovered. Specifically, we were not
properly setting the root sheet UUID. This was partially masked by a
const_cast setting of the RefDes in sch_symbol when called the RefDes
getter. This exposed the fact that our QA ERC numbers did not match the
schematic editor stand alone ERC numbers. So the test value for one
check needed to be updated

- Move PLUGIN_FILE_DESC to common.
- SCH_PLUGIN: rename Load -> LoadSchematicFile, Save -> SaveSchematicFile.
- Use PLUGIN_FILE_DESC and CanRead* in schematic plugins.
- Return none/unknown types from Find/GuessPluginType functions.
- Iterate over file types for file wildcards.
- Clean-up header checking in IO plugins.
- Use PCB plugin list in IO_MGR::GuessPluginTypeFromLibPath.
Also moves passive RLC inference out from migration to just-in-time
creation for the simulator or netlisting.
Also fixes a version guard mismatch because the spice migration was
done inside UpdateSymbolInstances (which has its own version guard).
Also changed UpdateSymbolInstances to UpdateSymbolInstanceData so
someone else in the future doesn't think it's a general-purpose symbol
instance updater.
