LUCENE-9615: Expose HnswGraphBuilder index-time hyperparameters as FieldType attributes (from Shubham Beniwal))

> HnswGraphBuilder has a few tunables: maxConnections, beamWidth, and we may add a few more, such as whether to use a diversity heuristic when choosing neighbors to link in the graph. Currently these are locked to defaults set by global variables. Instead we should provide some interface for configuring them. The best candidate so far seems to be to add them either as attributes on a FieldType, or as Codec level configurations.
