modules: canopennode: use zephyr/dsp/types.h for float32_t/float64_t

Include the zephyr/dsp/types.h header for float32_t/float64_t type definitions to avoid conflicts with other subsystems including this header. Add compile-time asserts to ensure the typedefs meet the requirements of the CANopenNode module. Fixes: #63896 Signed-off-by: Henrik Brix Andersen <[email protected]> (cherry picked from commit c9da682)
