ppapi: Add methods for sharing new shared memory classes with remote
This CL adds two new methods, ShareUnsafeSharedMemoryRegionWithRemote() and
ShareReadOnlySharedMemoryRegionWithRemote() to
ppapi::proxy::ProxyChannel::Delegate and to content::RendererPpapiHost classes
and all implementation classes.
These new methods are similar to the SharedSharedMemoryHandleWithRemote()
method in those classes but are supposed to work with the new shared memory
API.
