SOLR-9644: Fix boost handling in SimpleMLTQParser and CloudMLTQParser.
Both parsers tried to handle field boosts but didn't do it properly. This
pull request includes the following changes to both:
- Parse boosts from qf even if boost=false to avoid errors.
- Use the field names from the boost parsing so that they are always clean.
- Add tests for the same query with and without boosting.
Also fixed is an additional problem in CloudMLTQParser where it added
IndexableField type fields to the filtered document as is, which caused the
document to include field definition strings such as "stored" and "indexed".
This caused the MLT query to return records including these terms under some
circumstances.

properly and CloudMLTQParser to only extract actual values from IndexableField
type fields to the filtered document.

difference in results when boosting is used.
