Website pages now use fewer database requests and smarter caching so they can load faster for visitors. This improves the browsing and shopping experience, especially on high-traffic pages such as the online store.

Drastic website performance improvements

This Pull Request brings together a series of optimizations designed to significantly improve website performance by reducing database queries and accelerating page rendering.

The key changes are as follows:

Query and Prefetch Optimization: The code has been refactored to make the best use of Odoo's ORM prefetch mechanism. These changes allow for consolidating multiple data fetching queries into a single one, which improves overall efficiency and performance.

XML View Refactoring: The slow fields_get() method has been replaced with the _fields attribute in the template.layout view. This change is sufficient to check for a field's presence without overloading the system with unnecessary processing, resulting in a gain of approximately 8ms per page.

High-level Cache Introduction: A new cache has been added to the website.page model to store published pages. This cache can be controlled via overridable methods (_allow_to_use_cache, _allow_cache_insertion, _post_process_response_from_cache), allowing us to optimize rendering time for static or semi-static content.
This high-level cache on the `website.page` model, similar to the one that existed before the `t-cache` directive was implemented in `ir.qweb`.

see t-cache information and high-level cache (removed when introduce t-cache):

- https://github.com/odoo/odoo/pull/88276
When the previous high-level cache are removed: https://github.com/odoo/odoo/commit/0452d0701fcb8f4588b9b05dad9bbdd507539265
