CC3XX: Refine stdlib

Refine the cc3xx_stdlib module by exporting the define associated to the
maximum number of words to be copied using cc3xx_dpa_hardened_word_copy()
and introducing cc3xx_secure_erase_buffer() function that securely overwrites
buffer contents on deletion. It also increaes the constraint on the DPA-enhanced
word copy to support a maximum of 2048 bit copies.
