RFR: 8314502: GrowableArray: Make find with comparator take template

[Afshin Zafari]

The `find` method now is 
```C++
template<typename T>
int find(T* token, bool f(T*, E)) const {
...

Any other functions which use this are also changed.
Local linux-x64-debug hotspot:tier1 passed. Mach5 tier1 build on linux and Windows passed.
