RFR: 8299684: (bf) JNI direct buffer functions with large capacity behave unexpectedly [v12]

[Brian Burkhalter]

> Remove cast in `JNI::NewDirectByteBuffer`of `long` capacity to `int`, modify the constructor in question to accept a `long` capacity, and verify in the constructor that the  capacity does not overflow `int` range, throwing IAE If it does.
