Romain Derie a5a57321c7 [IMP] website: perf - reduce SQL queries for the website menu
Render page flow:
  - Search website.page in _serve_page for requested URL
  - Check if the page is visible with `is_visible`
  - `is_visible` will get the `ir.ui.view` of the page
    Note that this is not 'cachable' as being visible depends of now() for the
    publishing date
  - Render layout which is getting the website menus
    Note that this can't be cached either as a menu visibility might also
    depends of it's website.page visibility which depends of now()
  - Checking menus `is_visible` fetch the menus pages and those pages views.

Before this commit, every level of menu hierarchy would add 2 queries.
This can be avoided by prefetching everything in once during the dispatch if we
know we will render the website menu.
In such a case, read `is_visible` on every website menus will fetch every
pages, views and menus in the lowest SQL queries possible, eg one query for
every table.

For a 3 level menus, requests goes from 20 to 12 to load a untracked page.
