SDK:
* The TRACE_EVENT macro used to reject `const char *` event names: either
`StaticString` or `DynamicString` needed to be specified. In the last year
(since https://r.android.com/2494614), TRACE_EVENT mistakenly accepted
`const char *` as an event name. This has been fixed now. In case your
code fails to compile,
https://perfetto.dev/docs/instrumentation/track-events#dynamic-event-names
explains how to fix the problem.
