Revert "ecore_audio: a minimal template for playing sound on WINDOWS is added"

This reverts commit 7a98f617e94ef42787e06e685a8d5e7be34fff21.

this commit breaks compiling things against efl badly. i'm on holiday
and haver only a mini screen and keyboard wwith me so any serious wok
in hunting these issues isn't going to be fun or easy. as this causes
bad build brreaks this is worth a revert IMHO. please re-submit wwhen
you've tested against efl by building things against it. also our
public headers just should not have such ifdefs/if's that change api
presented based on how efl is cnfigured. we expose the same api and
macros and types regardless of internal config.
