Subject: Add BNTL utility plugin

Allow users to easily create, diff, dump and validate type libraries

Supports the following formats:
- C header files (via core type parsers)
- Binary files (collects exported and imported functions)
- WinMD files (via `windows-metadata` crate)
- Existing type library files (for easy fixups)
- Apiset files (to resolve through forwarded windows dlls)

Can be invoked as a regular plugin via UI commands or via CLI.

Processing of type libraries inherently requires external linking, processing will automatically merge and deduplicate colliding type libraries so prefer to use inside a project or a directory and process all information (for a given platform) at once, rather than smaller invocations.
