xaudio2: Use the preprocessor to modify definitions in xaudio2.idl and
xaudio2fx.idl.

Instead of including the IDLs directly, define a local IDL that #includes
them,
    with XAUDIO2_VER defined, and include that generated header.

Get rid of compat.c, and use XAUDIO2_VER to modify the code in the other
source
    files.

Build the tests for both xaudio2_7 and xaudio2_8 using PARENTSRC, and use
    XAUDIO2_VER to select between them. This mirrors the approach taken for
    d3dcompiler, and makes it easier to test more xaudio2 versions in the
future.
