include: move public headers to own directory

This ensures a clear separation between public and private headers. It
also makes it clear in Meson and prevents the accidental use of private
headers.

 ======================================
 
 mpv can be embedded into other programs as video/audio playback backend. The

+recommended way to do so is using libmpv. See ``include/mpv/client.h`` in the mpv
 source code repository. This provides a C API. Bindings for other languages
 might be available (see wiki).
 
 Since libmpv merely allows access to underlying mechanisms that can control
 mpv, further documentation is spread over a few places:
