Add compat flag forcing number of scene groups to query

[blhoward2]

Add a compat flag forcing the number of scene groups should be queried. Add to Leviton scene controllers. #2397

I'm unclear why we only query four scene IDs when there are eight.

Straight from the Z-Wave specs:
The Scene Controller Configuration Command Class is used to configure nodes launching scenes using
their association groups. [...]
The grouping identifier values MUST be a sequence starting from 1. The Association Supported Groupings
Get Command may be used to request the number of groupings that a node supports.

So, yeah... The device supports 4 association groups, so zwave-js queries 4 scene groups. There's currently no way to detect that there are in fact 8 groups. We'd need a compat flag for this.
