RFR: 8305104: Remove the old core reflection implementation [v2]

[Mandy Chung]

> JEP 416 integrated in JDK 18 and since then, only a couple minor issues has been reported.  Those issues were related with exception being thrown with invalid arguments.   We propose to remove the old core reflection implementation in JDK 22.  The `-Djdk.reflect.useDirectMethodHandle=false` workaround to revert to the old implementation will stop to work.
