[jdk17u-dev] RFR: 8293295: Add type check asserts to java_lang_ref_Reference accessors

[Aleksey Shipilev]

Maintenance backport: check that accessors are used for proper reference types. Helps to maintain GCs.

The backport is not clean, because we miss the hunk for `java_lang_ref_Reference::weak_referent`, added by Loom integration in JDK 19.

Additional testing:
 - [ ] Linux AArch64 fastdebug `tier1 tier2 tier3`
