Clean up KeyRangeIterator classes
* replace KeyRangeConcatIterator's PriorityQeueu with List
* remove KeyRangeIterator.current and simplify
* remove injected exception and tests - not relevant to the current implementation
* expand randomized testing
* inline getCurrent() -> peek(); rename getCount to getMaxKeys
* redefine skipTo contract to not return a value (which saves unnecessary work when skipTo is called multiple times in a row)
* calling hasNext in skipTo is a pessimization; if the iterator is in DONE state, then skipTo will see it and avoid further effort; if it is not, then we are computing a next value that we're just going to throw away
* fix SingleNodeQueryFailureTest - tests now multi and single index
* rationalize/standardize the way we release SSTableIndexes in QueryController

Upgrade to lucene-core 9.7.0
Notes on the upgrade path:
- RamIndexOutput is replaced with ResettableByteBuffersIndexOutput, an extension of ByteBuffersIndexOutput, which was the closest thing to a replacement of RamIndexOutput.
- Lucene exposes the code we needed from DirectReaders more or less directly in DirectReader now, so the old copied code has been deleted.
- Lucene changed its data files to be little endian, but to keep its compatibility story simple it retained BE for the header and footer ints. That's the cause of the changes in SAICodecUtils.
- We could gain a bit of performance making our own code natively little endian but that is too big of a change for this patch.
