Add new "uvm://" mount prefix to support cross-container
pipes for Xenon WCOW containers. For now, it's a WCOW-only
feature, while the Linux work is being prototyped.

Additionally, extend the logic of GetContainerPipeMapping to
also handle cross-container pipes within the UVM. The syntax
similar to sandbox mounts:

{
  "host_path": "uvm://\\\\.\\pipe\\uvmPipe",
  "container_path": "\\\\.\\pipe\\containerPipe"
}

Containers sharing the pipe need to have the same "host_path".
