[FIX] web: inline views should share their fields

Have a One2Many
The views of that o2m define two inline views: the list and the form

in the list view, put a field that isn't in the form and used in a domain
Try to add an item to the list
The form pops up

Fill in the data and save & close

Before this commit:
It crashed when evaluating the domain on a field using the field that is not in the form

After this commit:
Subviews share their fields in a special object on the parent record
In our case, the form view checks in that shared resource if the fields it is supposed to initialize
are there.
Hence, this flow doesn't crash anymore
