PR #75535 introduced trusted devices, but only made them visible in the
main user form (for admins) and in the portal.
It's quite useful for users to be able to view and manage their trusted
devices in their own user preferences as well.
This commit add them in the "Account Security" of the user profile.
In addition:
- improve the layout of the trusted devices by wrapping them in a
<group> to have them stand out from the surrounding prefs
- move the "Account is protected" label about the trusted devices, and
under main the 2FA toggle button, where it's supposed to be.
- removed the custom form view for trusted devices inside the one2many.
The point was to hide the extra `scope` field, but it's not worth it,
and the Cancel button wasn't even working, the default form view is
better.
- improve the confirmation message of the "Revoke All" button when it's
located on the user management form (for admins) to clarify that it's
not the admin's devices that will be revoked.
- change the 2FA label from "Your Account is protected" to "This account is
protected" when located on the user management form for admins.
Note: this is a manual partial fwd-port of #94111, as this part was
mistakenly dropped in the fwd-port chain at #94193closesodoo/odoo#94869
