Fix USE_MKLDN defaults (#50782)
Summary:
Fixes regression introduced by https://github.com/pytorch/pytorch/pull/50400
`cmake_dependent_option` semantic is following (see https://cmake.org/cmake/help/v3.19/module/CMakeDependentOption.html);
`cmake_dependent_option(<option> "<help_text>" <value> <depends> <force>)`
I.e. depends should be true for CPU_INTEL or CPU_AARCH64 but default value should be ON only if CPU_INTEL is true
