MDL-71970 h5plib_v124: Add namespace to H5P core library

The joubel/core is a third-party library. A namespace has been added to
avoid collision with other plugins using it (such as mod_hvp).
That way, they will be able to have a different version without
side effects.

 A PR has been sent to the H5P library with these changes:

 Hopefully, when upgrading, these patch won't be needed because it will be included in the H5P library by default.

+4. Add namespace to this library to avoid collision. It means:
+
+- Add the "namespace Moodle;" line at the top of all the h5p*.php files in the root folder.
+- Replace \H5Pxxx uses to H5Pxxx (for instance, in h5p-default-storage.class.php there are several references to \H5PCore that
+must be replaced with H5PCore).
+- Add "use ZipArchive;" in h5p.classes.h5p (check that it's still used before replacing it when upgrading the library).
