Optimize CDP Begin Blocker (#1822)
* optimize cdp begin blocker by removing unnecessary checks, reusing data
and prefix stores in loops, and reducing number of repeated calculations

* fix panic for new cdp types if both previous accural time and global
interest factor are not set

* do not touch global interest factor if no CDP's exist; revert to panic
if global interest factor is not found since this is an unreachable
state by normal keeper operation -- it can only be reached if store
is modified outside of public interface and normal operation
