RFR: 8353431: JFR: Sets to use hashmap instead of binary search as backend

[Markus Grönlund]

Greetings,

This enhancement is a simple set abstraction using a ResizeableResourceHashtable as a backend.

It provides two specializations, JfrCHeapTraceIdSet and JfrResourceAreaTraceIdSet, both tailored for keys of type traceid.

Sorted GrowableArrays used as sets have been replaced. 

Testing: jdk_jfr, stress testing

Thanks
Markus
