Changed default visibility for symbols in the PHP-CPP library to hidden and explicitly exported all symbols available from the public API. Moved the hiddenpointer to the zend implementation directory as it is not meant to be used publicly and not referenced anywhere from the API anyway

+/**
+ *  visibility.h
+ *
+ *  This file defines macros used to define whether a symbol
+ *  should be exported. It is only used for classes and
+ *  functions that are defined in the public API to reduce
+ *  the size of the symbol table, make linking and loading
+ *  of the PHP-CPP library faster and generate more
+ *  optimized code as a result.
