Meson was pretty strict about target ids and generating the mpv.com in
the same directory as mpv.exe wasn't possible. So as a workaround we
tucked it away in a subdirectory, but that's not really intuitive at
all. Well as of meson 1.3.0, this is now possible so leverage it since
it makes way more sense. We still keep the old workaround for anyone
using older meson versions.
This only existed as essentially a workaround for meson's behavior and
to maintain compatibility with the waf build. Since waf put everything
in a generated subdirectory, we had to put make a subdirectory called
"generated" in the source for meson so stuff could go to the right
place. Well now we don't need to do that anymore. Move the meson.build
files around so they go in the appropriate place in the subdirectory of
the source tree and change the paths of the headers accordingly. A
couple of important things to note.
1. mpv.com now gets made in build/player/mpv.com (necessary because of
a meson limitation)
2. The macos icon generation path is shortened to
TOOLS/osxbundle/icon.icns.inc.
