LOG: [CMake] Update CMake cache file for the ARM/Aarch64 cross toolchain builds. NFC. (#116744)

Forcely disable the libc++ benchmarks on Windows build hosts. The
benchmark configuration currently does not support the cross builds on
Windows hosts.

Also removed unnecessary `CMAKE_CROSSCOMPILING` CMake option.
