Fixes #20239: Prevent shared mutable state in PluginMenuItem and PluginMenuButton

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.
