[Android WebView] Tracing API: add trace argument filtering by default.

Add filtering of trace arguments data by default to the WebView Tracing
API. Only specifically whitelisted strings are allowed in trace args
to avoid exposing any potential PII and address privacy concerns.

Currently only a few metadata category events are whitelisted, e.g.
the "process_name", "thread_name" arguments which are useful for
viewing in "chrome://tracing".

If the developer preview is going out with m65, then the PII sanitization should be cherrypicked to m65, and a new build dropped.

This bug requires manual review: M65 has already been promoted to the beta branch, so this requires manual review
Please contact the milestone owner if you have questions.

Re #4: We are dropping M66 this week and not M65. No need to cherry pick this into M65
