Change TxtEdtEngine to return CFX_WideStringchromium/2935chromium/2934chromium/2933chromium/2932

This Cl updates the TxtEdtEngine and TxtEdtBuf to return CFX_WideStrings on
a Get instead of taking an out param. The change is propagated out through
the various Get methods that call into the edit engine.
