0271e39474 refactor(rdtsc): clean up tick logic, 
fix intrinsics, and resolve x86 compiler issues

- fix `time.hpp` compiler warnings (errors) and use proper intrinsic for gcc
- simplify tick calculation logic
- fix: exclude intrinsics include for non x86 builds and fix style
- fix: get() on clock_ unique ptr

dbc1b4439e feat: spoof rdtsc timings 
Previously, RDTSC in the VM always returned a constant value, which broke any non deterministic timing-based operations, or caused detections in heuristics of malware and ANTI-VM tools.

This patch introduces a spoofed rdtsc_fake counter that tracks and adjusts timing deltas to simulate realistic TSC increments. Can be extended to simulate rdtsc timings based on CPU clock speed.
