[UR][L0] Make IPC memory temporarily unsupported on Windows (#20993)

This commit changes the UR_DEVICE_INFO_IPC_MEMORY_SUPPORT_EXP query in
the UR Level-Zero adapter, making it return false on Windows. This is
done temporarily while we investigate the current failures related to
the UMF implementation of IPC on Windows.

See #20773.
