Use all text scorers in the final result to increase scoring signal (#26026)

* Uses all text scorers in the final result

- instead of just the maximum one
- add tests

* add prefix scorer test + fix text-score-with

* linter fixes

* pass in number of results to find

* refactor test function

* fix linter by removing unused namespace: metabase.util

* limit arity of serialize to 3

* make oss-score and ee-score different things

- They were defined to be exactly the same, but should be different!
- Update some tests that broke when a test function was fixed

* remove extra let

* move rseq back out of sorted-take

* improve test feedback

* force weight of text based scorers always weigh 10

* handle 0 score/weights when normalizing scores

* add nil check

* fix more subtle test differences

* more test fiddling

- still test that :offset and :limit respect limits

* reuse bit->boolean from api collection

* clean up some tests

- filter -> remove
- replace some magic numbers
- revert to testing entire maps instead of names of sorted items

* add test, docstring, and weight

* sort ns requires

* responding to most of the review comments

* start our zero-score sum check with 0

* do not tokenize / normalize nil raw-search-string

* force equality in basic search test

* modify test to work in dev and test environments

* use display_name in results when appropriate

- This was looking for the _first_ column that had a non-zero score, but
actually we need to consider all relevant columns.
- Uses them to figure out if there is a display name, and if there is,
to use it.
- Coppied over the logic about showing :context from the prior approach
