Trace Redaction - Filter suspend resume events

This starts a new pattern for some primitives. Rather than having
a single primitive build the allowlist, this allows multiple
primitives to contribute to the allowlist.

For this change, there is:

  1. a collect filter that adds the ftrace event id
  2. a ftrace event filter than filters suspend-resume events

As long as item 2 is registered, item 1 can be optionally added to
enable/disable suspend-resume events.
