mbedtls_ct_zeroize_if() function

Conditionally set a block of memory to zero. Regardless of the condition, every byte will be read once and written to once. \warning Unlike mbedtls_platform_zeroize, this does not have the same guarantees about not being optimised away if the memory is never read again.
