RFR: 8344262: Win32AttachOperationRequest objects are created by using global new

[Alex Menkov]

The issue was introduced by [JDK-8339289](https://bugs.openjdk.org/browse/JDK-8339289).
The fix makes `Win32AttachOperationRequest` successor of `CHeapObj<mtServiceability>`, so `Win32AttachOperationRequest` inherits its `new` operator
