RFR: 8261106: Reduce inclusion of jniHandles.hpp

[Ioi Lam]

niHandles.hpp is included by about 800 out of 1000 HotSpot .o files. Most of these are transitively included from these header files, which don't actually need to include jniHandles.hpp.

- ci/ciBaseObject.hpp
- ci/ciMetadata.hpp
- ci/ciObject.hpp
- classfile/moduleEntry.hpp
- gc/shared/gcVMOperations.hpp
- jvmci/jvmciJavaClasses.hpp
- runtime/thread.hpp
- services/threadService.hpp

Fixing these headers reduces the number of .o files that include jniHandles.hpp to 145.

Note: 43 files were changed in this PR. Most of them were using jniHandles.hpp but were not including it directly.

Tested with mach5: tier1, builds-tier2, builds-tier3, builds-tier4 and builds-tier5. Also locally: aarch64, arm, ppc64, s390, x86, and zero.
