Followup of #102259
Instead of adding a class to remove field borders, we want the opposite: hide the borders by default, except when specified specifically with a `.o_field_highlight` class (on a parent or the field itself). This makes it much easier to add field borders on specific parts of the ui (just add the class in the template), rather than having to _remove_ the class through a js override, which is far less discoverable.
I converted all the new rules to work opposite as before, same for the JS logic which added the class based on mobile device detection (size + touch support).
