feat(core): add client sync rules paramters

[DominicGBauer]

Description

Add params option in connect method of PowerSyncDatabase to allow users to set sync rules parameters from the client. To ensure type safety a new sealed class JsonParam was created so that params accepts a Map<String, JsonParam?>? which will prevent users erroneously including invalid parameters. Example usage:

    val params = JsonParam.Map(
          mapOf(
              "name" to JsonParam.String("John Doe"),
              "age" to JsonParam.Number(30),
              "isStudent" to JsonParam.Boolean(false)
         )
     )

   connect(
         connector = connector,
         crudThrottleMs = 2000L,
         retryDelayMs = 10000L,
         params = params
     )

Testing

I set new sync rules

bucket_definitions:
  list_buckets:
    accept_potentially_dangerous_queries: true
    parameters: select request.parameters() ->> 'listId' as list_id
    data:
      - SELECT * FROM lists where id = bucket.list_id

and passed a listId from the client side

db.connect(supabase, params = mapOf("listId" to "c3a57c9a-06e0-490a-9003-66cd838f7bde".toJsonParam()))
