pgAdmin 4 commit: Update "parse_priv_to_db" function to return list a i

Update "parse_priv_to_db" function to return list a instead of a string.

This will also allow us to operate on individual privileges & also we
needed this functionality for column nodes.

For example,

*Earlier:* priv was string

GRANT {{ priv }} ON {{ type }} TO {{ conn|qtIdent(role) }};

*Now:* priv will be List, which we need to handle in jinja templates.

GRANT *{{ priv|join(', ') }}* ON {{ type }} TO {{ conn|qtIdent(role) }};
