HltAsyncEventLoopMgr: backport fixes from HltEventLoopMgr
Port the following changes to the HltAsyncEventLoopMgr
that were missed in the original fork (!69464 (merged)):
- set the default of
HltAsyncEventLoopMgr.setMagFieldFromPtree
totrue
(145e0240) - Use C++17 std::filesystem instead of boost::filesystem where possible (2b7217bc)
- only send event to debug stream if severely truncated (34b5d520)
None of these have any impact on P1 operations.
Relates to ATR-26285.
