Add field as a separate input to newSynonymQuery (#11941) 
QueryBuilder#newSynonymQuery takes an array of TermAndBoost objects as a
parameter and uses the field of the first term in the array as its field. However,
there are cases where this array may be empty, which will result in an
ArrayOutOfBoundsException.

This commit reworks QueryBuilder so that TermAndBoost contains plain
BytesRefs, and passes the field as a separate parameter. This guards against
accidental calls to newSynonymQuery with an empty list - in this case, an
empty synonym query is generated rather than an exception. It also
refactors SynonymQuery itself to hold BytesRefs rather than Terms, which
needlessly repeat the field for each entry.

Fixes #11864

Building

Basic steps:

  1. Install OpenJDK 17 or 18.
  2. Clone Lucene's git repository (or download the source distribution).
  3. Run gradle launcher script (gradlew).

We'll assume that you know how to get and set up the JDK - if you don't, then we suggest starting at https://jdk.java.net/ and learning more about Java, before returning to this README.

See Contributing Guide for details.
