Remove ENCA support

There is no real value in it. ENCA only works in some cases and I
can't find any information about software that integrates libass
which relies on it or users that rely on ENCA support in case the
interface is exposed directly (e.g. in MPlayer).

If there is still a wish to have charset detection integrated into
libass (it is out of scope, IMHO), a better library like uchardet
should be used for that.
