RFR: 8264309: JFR: Improve .jfc parser

[Erik Gahlin]

Hi,

Could I have a review of a fix that removes unnecessary number of allocations of StringBuilders. Events are now referred to by name, not path. The code should reflect that. The method getSettings() is not used and can be removed.

Testing: jdk/jdk/jfr

Thanks
Erik
