RFR: 8361447: [REDO] Checked version of JNI Release<type>ArrayElements needs to filter out known wrapped arrays

The original PR (https://github.com/openjdk/jdk/pull/26123) had incorrect usage of `SafeFetch32`. This PR replaces that with the use of `os::is_readable_range` as proposed by @tstuefe  (thank you!). In addition I found that code was no longer getting exercised by the regression test so I added a gtest for that (during which it was discovered that the new implementation in `verify` requires any gtest that uses it to be `TEST_VM` rather than `TEST`).

Testing: tiers 1-4

Thanks
