William Beasley (The Capable Hub) ba0122628c cheri: Use conditional copy over bitmask arithmetic in sakke_modexp_loop ...

On CHERI casting mp_int pointers to wc_ptr_t for the bitmask
arithmetic strips the hardware capability tag. The reconstructed
pointer won't have a valid tag and will cause a tag violation when it
is dereferenced.

Under __CHERI_PURE_CAPABILITY__, replace the pointer arithmetic with
four mp_cond_copy calls that operate on the digit data directly.
This preserves the capability tags and accesses both accumulators
unconditionally.

Non-CHERI builds retain the original wc_off_on_addr path unchanged.
