[FIX] web: form: hide labels of oe_(read|edit)_only fields

In a form view, nodes with classname "oe_read_only" (resp.
"oe_edit_only") are only visible in readonly (resp. edit) mode.
Moreover, fields inside a group automatically have an associated
label.

Before this commit, when one of these classnames was set on a
field node inside a group, the effect wasn't applied on its label,
so the label was always visible, even if the field was hidden.

closes odoo/odoo#48968
