Fixed UIA pattern matching for IExpandCollapseProvider.

[boydpatterson]

What does the pull request do?

UIA pattern matching was looking at a Win32 interface for IExpandCollapseProvider instead of the Avalonia-specific implementation of an interface with the same name.

What is the current behavior?

No AutomationPeer classes properly support expand/collapse with UIA.

What is the updated/expected behavior with this PR?

Any AutomationPeer class that implements the IExpandCollapseProvider interface will work with UIA.

How was the solution implemented (if it's not obvious)?

Corrected type reference with namespace qualifier.
