Before this commit, website.page xml record were created in 2 steps:
1. Create an ir.ui.view record with <template> tag
2. Create a website.page record with <record model="website.page">
But this is useless since website.page inheritS ir.ui.view, you can create both
records just in one <record> tag.
Note: This is NOT TRUE in every case:
Odoo's ORM will suffix external_id of inherited records (in this case the
ir.ui.view created through the website.page record) with its model's name.
This can be a problem in some case (this is an example):
website_crm_template.xml create an ir.ui.view inheriting the
ir.ui.view 'website.contactus'.
But if we didn't keep website.page & ir.ui.view records split for that
specific case, the ir.ui.view would inherit a website.page record
causing an error. (website.contactus would be the id of the page record
while the ir.ui.view's id would be website.contactus_ir_ui_view)
In short: when migrating an ir.ui.view (<record> xml) to a website.page:
* If there is record inheriting the ir.ui.view ID, then split
website.page & ir.ui.view
* if not, you can create the website.page and its ir.ui.view both in one
record (<record model="website.page").
This commit also removed remaining page="True" from xml template since we
removed the 'page' attribute from ir.ui.view model overrided in website module.
