Adrien Grand 9ab324d2be Allow reusing indexed binary fields. (#12053) 
Today Lucene allows creating indexed binary fields, e.g. via
`StringField(String, BytesRef, Field.Store)`, but not reusing them: calling
`setBytesValue` on a `StringField` throws.

This commit removes the check that prevents reusing fields with binary values.
I considered an alternative that consisted of failing if calling
`setBytesValue` on a field that is indexed and tokenized, but we currently
don't have such checks e.g. on numeric values, so it did not feel consistent.

Doing this change would help improve the [nightly benchmarks for the NYC taxis
dataset](http://people.apache.org/~mikemccand/lucenebench/sparseResults.html)
by doing the String -> UTF-8 conversion only once for keywords, instead of once
for the `StringField` and one for the `SortedDocValuesField`, while still
reusing fields.

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.
