Implement test cases for `IXMLDOMElement_removeAttributeNode()` function. Cover the successful removal and failure codes for double removal and `NULL` pointer removal.
The function is currently unimplemented in wine.
This is the recommended first step according to the contribution documentation (do coverage MR first, then implementation MR).
WineTestBot submission can be found here: https://testbot.winehq.org/JobDetails.pl?Key=159816
Once this one is merged I'll create the implementation MR.
I tried to match the formatting. If I've missed something please tell me and I'll fix it.
edit: remove mention of failing tests, update WineTestBot link, fixed by rebasing on 3cfbf9e3cd99dd01d3215c6952ae18ce88207d22
