Convert string Find methods to return an Optional
The Find and ReverseFind methods for WideString, WideStringC, ByteString, and ByteStringC have been converted from returning a raw FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure can be indicated without using FX_STRNPOS. This allows for removing FX_STRNPOS and by association makes the conversion of FX_STRSIZE to size_t easier, since it forces checking the return value of Find to be explictly done as well as taking the error value out of the range of FX_STRSIZE. New Contains methods have been added for cases where the success or failure is all the call site to Find cared about, and the actual position was ignored.
