Some Windows SDK classes, for example Windows::Storage::Streams::IBufferByteAccess, use the ATL way of spelling attributes:

  [uuid("....")] class IBufferByteAccess {};

To be able to use __uuidof() to grab the uuid off these types, clang needs to support uuid as a Microsoft attribute. There was already code to skip Microsoft attributes, extend that to look for uuid and parse it (using the existing code to parse the same attribute in __declspec). Add a new "MS" attribute type for this syntax.

There's already a function that moves attributes off the declspec into an attribute list for attributes applying to the type, teach that function to also move MS attributes around.  This requires that MS attributes make it to the DS in the first place, so move the call to MaybeParseMicrosoftAttributes() into ParseDeclOrFunctionDefInternal() so that it can store its results in DS.getAttributes().
