You can set the engine as a file variable in the files which require
XeTeX.
For example like this:
%%% Local Variables:
%%% mode: latex
%%% TeX-engine: xetex
%%% TeX-PDF-mode: t
%%% TeX-master: t
%%% End:

AUCTeX uses style files for things like this. For example for
fontspec.sty you'd write a file called fontspec.el which is placed in
AUCTeX's style directory and which switches the TeX engine to XeTeX.
See (info "(auctex)Style Files") for details.
