This update prepares Odoo for OWL3 by automatically adding `.this` to template variables that reference component data. This change is necessary because OWL3 requires a specific syntax for accessing component variables within templates, ensuring compatibility with the new OWL3 environment. The changes impact several Odoo modules, primarily within the web_studio environment.

In preparation for OWL3, where template variables will need to use `.this` to target component variables, we add `.this` to template variables that are targetting the component.
