[IMP] documents{_hr|_spreadsheet}: improve share panel

We convert the share panel in a wizard and improve it by allowing sharing multiple documents at once.

Technical notes:
- if we set partner_id and documents_share_id fields as required in documents_share_access, it doesn't work (ex.: wizard button not updated when deleting an access).
- if we set original_role as required in documents_share_access, it cause a validation error when updating the role when the wizard is saved (original_role is empty while it has been initialized with a value). We cannot set it readonly either (cause "format requires a mapping" error).

[IMP] documents: improve document search

We add a "shared with" in quick search to easily look for all documents/folders shared with a contact.

And we add the following filters:
- to display all files and folder in anyone with the link.
- to display only images and videos
- to display only URL

[IMP] documents: add an option to avoid propagate rights
