Add a new LPM fuzzer for Mach message servers.
This fuzzer tool allows modeling the complex Mach IPC structures,
including the generation and transfer of port rights. It also adds a
build rule to convert textproto to binarypb, so that the seed corpus for
these fuzzers can be human-editable/readable.
Adds a simple fuzzer for the MachPortRendezvousServer.
