fix performance regression for Site save, use bulk_update for cached fields

PluginMenuItem and PluginMenuButton classes used mutable class-level
defaults for `permissions` and `buttons` attributes, causing permission
leakage between instances when these attributes were modified without
explicit parameters.

Changed to initialize these attributes as fresh lists per instance in
__init__ when not explicitly provided, following standard Python pattern
for avoiding mutable default arguments.

+When creating, modifying, or deleting an object in NetBox, a user has the option of recording an arbitrary message (up to 200 characters) that will appear in the change record. This can be helpful to capture additional context, such as the reason for a change or a reference to an external ticket.
