Throwing EOFException when reading past eof [LUCENE-9296]

When reading past eof, lucene can throw three types of exceptions. 

org.apache.lucene.store.BufferedIndexInput#readBytes throws EOFException

org.apache.lucene.codecs.compressing.CompressingTermVectorsReader.TVPostingsEnum#nextPosition throws IllegalStateException

org.apache.lucene.queryparser.classic.FastCharStream#refill throws IOException

When I implement my code, I have to handle three types of exceptions. Can the exceptions be made consistent? I feel that EOFException is the most reasonable exception.

Migrated from [LUCENE-9296](https://issues.apache.org/jira/browse/LUCENE-9296) by Hao Zhong

Start by comparing BufferedIndexInput#readBytes, CompressingTermVectorsReader.TVPostingsEnum#nextPosition, and FastCharStream#refill, focusing on their behavior when reading past EOF. The work is done when these entry points consistently use EOFException instead of the currently mixed exception types.
