[PATCH 1/4] include: Add windows.media.speechsynthesis.idl draft.

[Rémi Bernon]

This IDL is used by windows.media.speech.dll, which is itself required
by Flight Simulator. It will here be used as an illustration and test
case for WIDL WinRT features.

Signed-off-by: Rémi Bernon

This is the beginning of a series to correctly support parameterized
interfaces in WIDL in WinRT mode. I'm using this new idl file as well
as windows.foundation.idl to illustrate and test the parsing features,
and the generated headers.

The generated code should closely match MIDL this time, at least on the
C side. The C++ side of the WinRT generated headers are based template
implementation classes from internal WinRT headers, which we don't have
and that will require a lot more work to figure how to do it properly.
