[NCE] Fix cache invalidation and signal interrupt race condition (#3063)
Inspired by PR #3047
This should theoretically fix 3 bugs in NCE:
- **Bug 1**: `ClearInstructionCache()` now properly invalidates L1 instruction cache using IC IALLU instead of only using memory barriers
- **Bug 2**: `InvalidateCacheRange()` implements proper range-based cache invalidation instead of always flushing entire L1 cache
- **Bug 3**: `SignalInterrupt()` adds acquire fence to guarantee memory visibility of the `is_running` flag, preventing lost signals
