Use the agreed upon include path for spirv-cross.

Everyone using spirv-cross includes its headers via <spirv_msl.hpp> for
example. Make Dawn match that convention so it can play better with the
setup used by other projects.

Still leave <spirv-cross/spirv_msl.hpp> working for now because it is
used by shaderc_spvc. A follow up CL to that repo will do the same
change.
