Update USE_XCCL option if USE_XPU is OFF (#153936)

Browse Source 
# Motivation
Disable `USE_XCCL` when `USE_XPU` is turned `OFF` to ensure configuration consistency. This is required because XCCL depends on XPU functionality.
Especially, ensure that `USE_XCCL` is correctly set to `OFF` when [caffe2_update_option(USE_XPU OFF)](1075bb37d3/cmake/Dependencies.cmake (L97)) is invoked.
