Fix SafeHandle marshalling in ref/in/out parameters (mono/mono#17330)

Fix SafeHandle marshalling in ref/in/out parameters (mono/mono#17330)

* Fix SafeHandle marshalling in ref/in/out parameters

* Reorder code to make it exception safe, update comments

* Revert the code reordering because it breaks the invariant that new handle returned from native code should always create new SafeHandle on the managed side

* Fix test_0_safehandle_ref test. The test was expecting incorrect behavior, verified on .NET Core 3 and .NET Framework 4.8.

* Address PR feedback

* Fix cut & paste error

* Fix build

* Really fix the test_0_safehandle_ref tests

* Add more tests for SafeHandle marshalling

* Add exclusion for broken CoreFX test
