8346237: Obsolete the UseOprofile flag

[dholmes-ora]

The UseOprofile flag is obsoleted in JDK 26 and so the code associated with it is removed. That means linux_wrap_code is dead code and consequently CodeHeap::on_code_mapping is also dead code.

Testing:

• tiers 1-3 sanity

This comes from JDK-6265868. Nice to remove this. Looks like we obsoleted this code a long time ago.
