Remove deprecated symbols from recent_blockhashes_account (#2004)

* Move recent_blockhashes_account to runtime

* Fixup imports

* Reduce pub

* Remove unused method

* Duplicate code to limit pub and dependency complexity

* Move test-only fn into tests module

(cherry picked from commit f77658b)
