Fix user set SCI_SETYCARETPOLICY erase by find result

Use SCI_SETVISIBLEPOLICY and SCI_ENSUREVISIBLEENFORCEPOLICY to replace SCI_SETYCARETPOLICY.
X and Y caret policy should be user-configurable for document navigation and the VISIBLE / ENSUREVISIBLE could be used for application / auto navigation (like re-centering a search result).

Fix #8961, close #8962
