Elevate DenoPermissions lock to top level

[kevinkassimo]

• Remove independent per detailed state atomics
• Wrap DenoPermissions in Arc<Mutex<...>> instead
• Add argument shared_permissions to allow passing down a Arc<Mutex<DenoPermissions>> to share with another state

This refactoring is to allow cloning permissions easier. The general idea is to separate the below behaviors in the future:

• Worker copies permissions from global
• Worker inherit permissions from parent, updating one of which is reflected to another
• Worker copies permissions from parent, but future updates on either side are not reflected
• Worker copies partial permissions or no permissions from parent
