Enable Thread Safety Annotations for Perfetto standalone builds.

- Add 'thread_annotations.h' that contains thread safety macros, copied from the Chromium repo with the 'PERFETTO_' prefix add.
- These safety macros are expanded into no-op if the 'PERFETTO_THREAD_SAFETY_ANNOTATIONS' build flag is not defined, which allows us to build non-standalone builds without enabling thread safety analysis.
- Annotate mutex usages in 'src/base/' and 'include/perfetto/ext/base/'.

See https://clang.llvm.org/docs/ThreadSafetyAnalysis.html for details on how thread safety analysis works.

Perfetto - System profiling, app tracing and trace analysis

Perfetto is a production-grade open-source stack for performance instrumentation and trace analysis. It offers services and libraries and for recording system-level and app-level traces, native + java heap profiling, a library for analyzing traces using SQL and a web-based UI to visualize and explore multi-GB traces.
