[Star tree] Handle 'unsigned long' as part of star tree

[bharath-techie]

Is your feature request related to a problem? Please describe

Unsigned long in number field is stored as Java.Long when we store as part of doc values and as part of star tree node.

So when unsigned long is > Long.maxValue , the values become negative and hence we need to handle unsigned long comparison separately.

Describe the solution you'd like

We can use Long.compareUnsigned(long, long) as part of dimension sorting.

We also need to handle min , max comparisons as part of aggregations.
