No method was readily available to know if a user is `internal` (has
group `base.group_user`), which was inconsistent with other base groups.
_is_internal is now used in the codebase where it is clear that
`.has_group('base.group_user')` is called on a single record.

When portal is not installed and `auth_signup.invitation_scope` is "b2c",
visitors can create an account, leading to a blank page. Still, accounts can be
required for several use cases in apps that do not require portal (such as
survey).
We here add a landing page for users that created an account but have no
requested redirections and cannot be redirected to a customer portal either.
auth_signup_uninvited is also updated in model to be consistent with config
data.
Tests are added to check this behavior.

The odoo.addons.web.controllers.main module was a very long bloated file
where many different controllers were concatened. It proved difficult to
work on that file on a regular basis,mainly because ctrl-p "web main.py"
was not pointing the right file.
In this work the file has been split on the basic 1 controller = 1 file.
The original way of importing stuff (through main.py) is still possible
thanks to deprecated aliases.
