Add views filter support

For me it will be useful if we can export certain attribute in json as exposed filter.

With help of AI, I made proof-of-concept for this, works only with MariaDB/MySQL.
Would require more work for sqlite and postgresql.

Thanks for the PoC.

I left you a couple nits in Slack but I wanted to note: as far as I can tell user supplied jsonpath goes into the query unescaped, that looks like
a problem to me.

Also, , this is what backend overridable services were invented for. I would put the mysql specific logic into one such making eventual postgresql and sqlite implentations seemlessly integrate.

services:
  json_field.query:
     class: this could be an abstract class
    tags:
      - { name: backend_overridable }
  mysql.json_field.query:
     class: Some\Helper\Containing\The\MySQL\Logic

Check the views.date_sql service and friends for an example.
