Cache parsing attr in LazyState

[bdraco]

Proposed change

Parsing attributes in the most expensive part of loading a LazyState

This speeds up history requests for entities where cannot use minimal_response or are in NEED_ATTRIBUTE_DOMAINS

On a few of my production instances attributes ranged from 82-88% duplicates of another set of attributes.
