RFR: 7948: Update ASM to 9.7 so the agent can build and run with JDK17

[Joshua Matsuoka]

Addresses JMC-7948 (Update ASM version in the agent).

The agent currently uses a very old version of ASM that doesn't support more recent JDK versions (most notably JDK17).

This PR bumps the ASM version up to 9.7 which was released in March and supports up to JDK23. It also bumps the agent build up to JDK17.
