Pull Request Overview

This PR removes the DB_IPCE_LOAD_ASSEMBLY event mechanism from the CoreCLR debugger interface. The change consolidates assembly loading notifications by moving the assembly loading callback functionality into the existing module loading event handling instead of maintaining a separate assembly loading event.

Key changes:

• Removes the separate DB_IPCE_LOAD_ASSEMBLY event type and associated infrastructure
• Moves assembly loading callback invocation to occur during DB_IPCE_LOAD_MODULE event processing
• Updates assembly notification logic to use module load flags instead of assembly load flags
