LUCENE-9970: Add TooManyNestedClauses extends TooManyClauses so that
IndexSearcher.rewrite can distinguish hos maxClauseCount is exceeded
This is an extension of the work done in LUCENE-8811 which added the two types
of checks

> Historically, if {{TooManyClauses}} was thrown it meant exactly one thing:
> That a QueryX Builder (typically BooleanQuery, but there are a few others in
> sandbox) was not going to allow it's caller to add a clause because that
> QueryX object already had the maxClauseCount in _direct_ children.
> LUCENE-8811 added an additional "reason" why {{TooManyClauses}} may be thrown
> starting in 9.0: IndexSearcher may now throw this exception if the
> (rewritten) Query being executed has a _cumulative_ number of clauses –
> across the entire structure of _nested_ Query objects – that exceeds the
> maxClauseCount.
> ----
> I think it would be helpful to users if it was possible to tell from the
> {{TooManyClauses}} exception how the maxClauseCount was exceeded (because of
> the total number of direct children during rewrite, or cumulatively across
> the entire nested structure) w/o needing to inspect the stack frames to see
> if the thrower a rewrite method, or a QueryVisitor method.
