Natvis support for hresult_error and array_view

[oldnewthing]

hresult_error displays the wrapped hresult.

array_view displays the size and the first few elements. It expands to the elements in the view, in the form of an array.

Might be harder but it would be nice if hresult_error's natvis could display the restricted error information, if any, since sometimes you have a useless error code ("Catastrophic failure") but a good description of the issue in the stashed IRestrictedErrorInfo*

[oldnewthing]

Yes, it would be nice. But it's also harder.

That would require a debugger extension for runtime execution of code, not something the natvis format itself supports.
