Subject: [PATCH] Add IsStringInternProperty to BinaryPropertyAccessorBase

Introduce IsStringInternProperty to cache the [AcStringIntern] attribute value for each property. Update the constructor to initialize this property, and revise class documentation to reflect the new addition. This enables efficient access to string interning settings per property.
