cmake: add option ENABLE_WINE to enable support for running cross compiled tests with wine

For details about the ENABLE_WINE option, which support three modes
AUTO|ON|OFF see the documentation of cmake macro check_auto_option().

A custom path for the wine executable can be specified by adding
-DWINE_EXECUTABLE=<path> to the cmake command line.
