RFR: 8318609: Upcall stubs should be smaller

[Martin Doerr]

We can use `resolve_global_jobject` (introduced by [JDK-8299089](https://bugs.openjdk.org/browse/JDK-8299089)) because we know that the handle is created by `JNIHandles::make_global` in `UL_MakeUpcallStub`. That creates much shorter code.

Size reduced from 1360 bytes to 648 bytes on x64.
