[reland] Mojo: Introduce public PlatformHandle type
Reland of r560866, which was missing an include for Fuchsia in some
configs.
Adds mojo/public/cpp/platform to the public library. This includes
a new PlatformHandle type, a thin C++ abstraction for platform-specific
scoped handle values.
This is a precursor to moving platform channel C++ types out of the EDK
and into the public library, and ultimately introducing a public C++
invitation API to replace the EDK invitation API.
