Investigate ARM64 CFG failures when using the dispatcher

[jakobbotsch]

Description

In the original PR I had a mistake in an ifdef chain that caused us to never enable the dispatcher, even when trying to forcibly enable it via environment variables (by default, ARM64 does not use the dispatcher). #65095 fixed it and there are interesting failures in the jit-cfg run there that should be investigated.

Reproduction Steps
