[FIX] web,(various): don't pollute session_info for portal users

The `session_info` dictionnary is used to bootstrap some JS code client
side (usually in the backend). It includes relevant information, such
as some parameters key for the OdooBot onboarding, the Enterprise
subscription expiration alert, etc. to avoid triggering a lot of RPC
calls upon webclient start.

`session_info` is also called by the remote authentication mechanism
located at `/web/session/authenticate`, which can be used by external
mechanism to obtain a valid session remotely.

Revision odoo/odoo@8a28cc2 introduced the concept of cache keys for
some oft-requested data (such as menus, translations and dynamic qweb
templates) to avoid requesting them on each webclient start, since they
tend not to change often. Unfortunately, it introduced a read on the
ir.ui.menu model that raised an `AccessError` if the authenticating user
was not a member of the `base.group_user` group ('Internal' user type).

While fixing that issue, it became apparent that `session_info`
returns a whole lot of information through this remote connection route
which is entirely unnecessary if not used in the context of a webclient
start, such a currencies, the state of the enterprise subscription, etc.

This commit fixes the access right issue by removing this non-relevant
information from the returned dict (including cache keys) if the user
is not an internal one.
