cdde68d5 - [SYCL] Fix build with disabled preview library (#21250)

[SYCL] Fix build with disabled preview library (#21250) Currently configure.py fails if `-DSYCL_ENABLE_MAJOR_RELEASE_PREVIEW_LIB=Off` is passed. This patch enables preview unittests only if `SYCL_ENABLE_MAJOR_RELEASE_PREVIEW_LIB` is ON.
