Specify input .winmd files in windows-bindgen

[Alovchin91]

Motivation

Currently windows-bindgen crate seems to always look for .winmd files in .windows subdirectory. There should be a way to specify input files/directories.

Drawbacks

The need to specify input path, or a more complex logic selecting defaults

Rationale and alternatives

When generating a .winmd file (see WinRT component sample), I would like to put it into cargo’s $OUT_DIR and then generate a projection from it.

Additional context

Yes, the underlying reader used by the bindgen crate is shared by the older gen crate. Once I've finally removed the gen crate this should be simpler and I expect the bindgen crate simply to rely on procedural input to declare winmd files.
