RFR: 8307362: Remove test com/sun/jdi/JdbLastErrorTest.java

[Kevin Walls]

This should be a trivial change, to remove a test which is unreliable, and to remove its problem list entry.

The test is unreliable, but also the updated Panama situation is that we now have Linker.Option.CaptureCallState which gives us the chance to capture last error when calling a MethodHandle, and read the stored last error code in a VarHandle.  This is the way to reliably capture a last error value, and is tested in test/jdk/java/foreign/capturecallstate/TestCaptureCallState.java.

The JdbLastErrorTest should be removed.
