[FIRRTL] Add GroupSink pass #6184

  1. [FIRRTL] Add very simple GroupSink pass 

    Add a new pass, GroupSink/firrtl-group-sink, which will sink operations
that are only used by optional groups into optional groups.  This is very
simple at present.  This pass uses `mlir::controlFlowSink` to sink ops
into regions.  This only works for very simple things in FIRRTL which have
normal SSA dominance, e.g., nodes, constants, or primitive operations.

firtool pipeline just before LowerGroups.
