Pull request overview
This PR disables SVE (Scalable Vector Extension) intrinsics when the interpreter is enabled in the CoreCLR runtime. The change addresses an architectural incompatibility where SVE's FFR (First-Fault Register) requires per-method saved logical state that the interpreter does not currently support.
Changes:
- Added a conditional check to disable SVE intrinsics when the interpreter is active

SVE intrinsics support for the FFR register adds a new concept of per method saved logical FFR state which the interpreter does not model.
