[otbn,rtl] Separate wipe value of last WDR and ACC register

Prior to this commit, WDR[31] and the ACC register had the same value
after secure wipe (#14324).  This commit fixes #14324 by extending the
secure wipe by one cycle, so that WDR[31] is now wiped in the cycle
before the ACC register is wiped.
