Silence false CodeQL issue and update event_session::name() doc

Browse Source 
LoggerNameOffset represents offset (in bytes) from the start of the prop
to the beginning of the null-terminated string that contains the session
name. Hence, the prop must be cast from EVENT_TRACE_PROPERTIES* to char*
or BYTE* first, to calculate address properly.
