Passing params/references to groups/adapters

Summary of the new feature / enhancement

dsc only has visibility in the top most layer. This means that functions that get called such as parameter() and reference() can only access those within the same layer. A group can access those functions, but only within that group's layer.

Currently, there isn't a way to pass parameters to groups and a group cannot access a reference outside of its layer.

Proposed technical implementation details (optional)

I think we are ok to say that reference only works within a group, but I can see utility in passing parameters lower. In the case of groups, we could define a new to pass parameter values with the expectation that the either the group has a literal parameters section it resolves or we can have it inherit the parent's parameter definitions.

For adapters, we may just not have support for either.

Start by tracing how dsc resolves parameter() and reference() visibility across layers, then inspect the group and adapter handling described in the issue. The payload names no files or tests, and done is not defined beyond deciding and implementing how parameters should reach groups and whether adapters support them.
