Commit ba75dc5e6bf7e90b8c40906ba8ca7b258a5b39c0 in lucene's branch refs/heads/main from Robert Muir

LUCENE-10150: override ByteBuffersDataInput readLong/readInt/readShort

Optimize these relative-read methods to no longer read
one-byte-at-a-time.

This speeds up common scenarios such as reading postings from in-memory
directory / nrt-caching directory.

> This DataInput optimizes readFloats() with a FloatBuffer view, but does nothing for readLongs().
> Currently readLongs() will read the entire array one-byte-at-a-time.
> With LUCENE-10149, it will go eight-bytes-at-a-time.
> But we could override this method and optimize it further, to reduce bounds checks and speed up postings.
