perf: Blink / AddOnly SortedFirstOrLast, use explicit comparison oper…

…ator (#5818) This is handling a subset of SortedFirstOrLast operators; the general case which goes through `io.deephaven.engine.table.impl.by.SortedFirstOrLastChunkedOperator` / `SegmentedSortedArray` is a larger change that should land independently. The logic is identical, but this provides the JVM a more specific target to optimize.
