RFR: 8366905: Store AdapterBlob pointer in AdapterHandlerEntry

Fri Sep 5 19:30:27 UTC 2025

This PR removes the need to store entry point addresses in AdapterHandlerEntry by storing a direct pointer to AdapterBlob instead. Entry point addresses can be computed on the fly from the entry point offsets stored in AdapterBlob.
