We want to enable backtrace_decoding for all of the performance tests

but enable it means we'll be decoding all of the reactor stalls, which is causing lot of waste for performance test

we need a new configuration option backtrace_stall_decoding that would skip decoding only on stall, and still decode other events

(advanced option backtrace_decoding_disable_regex that can work base on the some data of the events, type or other context)
