4225: [EXP] Let the user customize the proximity precision r=dureuill a=ManyTheFish

# Pull Request
This PR introduces a new setting `proximityPrecision` allowing the user to trade indexing time with search precision on proximity-based features:
- proximity ranking rules
- multi-word synonyms
- phrase search
- split-words

I put the API PRD below:
https://www.notion.so/meilisearch/3988b345b5b248948a4a0dc5932a18ce?v=45d79150adb84b0aa27826ff6da2e029&p=aa69c2bab2c3402bab9340ae4def4577&pm=s
