We need to support the Text pattern on text leaves to fix issues with Narrator. Removing support on the root isn't strictly necessary, but the Text pattern isn't normally supported on a UIA Window and Chromium doesn't do this, so I think it's best to follow. This change necessitated moving UiaText so that it is no longer inherited by ia2AccessibleHypertext. I initially tried to inherit UiaText into uiaRawElmProvider, but that doesn't work because ITextProvider and ISelectionProvider both have a GetSelection method with the same signature. This meant that the ISelectionProvider implementation of GetSelection in uiaRawElmProvider was overriding the implementation in UiaText. Instead, UiaText has now been split into a separate object.
