Make IPC macros work with -Wunused-local-typedefs.
The typedef can be used by the IPC_MESSAGE_HANDLER macro, but that macro isn't
always used when IPC_BEGIN_MESSAGE_MAP is used. The alternatives are to either
pass ClassName::HanderFunction to IPC_MESSAGE_HANDLER (like what one has to do
to use IPC_MESSAGE_FORWARD), or to mark the typedef in IPC_BEGIN_MESSAGE_MAP
as ALLOW_UNUSED so that it isn't warned on.
