[FIX] ir.ui.view: properly validate newly created inheriting views

    When a new inheriting view is imported during a module
    installation, it is validated thanks to the _constraints
    on the ir.ui.view model. However the validation uses
    a rather convoluted system for validating the whole
    view tree at once (root view + all inherited changes)
    while only taking into account the views that belong
    to modules that are currently loaded.

    This complicated system is necessary to be able to
    operate on-the-fly at any point during the registry
    loading/initialization.

    Now because _constraints are checked during create()
    this particular validation happens *before* the
    external ID (ir.model.data entry) of that new view
    can be created (it obviously needs to wait until
    the view record is inserted). As a consequence the
    view validation cannot determine the module to
    which that new view belongs, and was erroneously
    ignoring it.
    Changing the view filtering to also include views
    that have triggered this check.
    Manually created views are not check during registry
    update.
