Space Meyer a721e4d507 Kernel: Track KCOVInstance via Process instead of HashMap ...

While this clutters Process.cpp a tiny bit, I feel that it's worth it:
- 2x speed on the kcov_loop benchmark. Likely more during fuzzing.
- Overall code complexity is going down with this change.
- By reducing the code reachable from __sanitizer_cov_trace_pc code,
  we can now instrument more code.
