Check for permissions when filtering supported events

[vhotspur]

Currently, the filtering of supported events is based solely on the ability to resolve the event name.

But when running in some kind of sandbox, the event may exist but may not be available due to other restrictions.

For PAPI events, we should create a dummy event set, add the event there and only if this is OK we can mark the event as supported.

This is easily demonstrated on CI builds on GitHub actions where PAPI is available but no events are permitted.
