[roll] Roll fuchsia [superproject] Roll third_party/Vulkan-Loader [Vulkan-Loader] Ensure directories have read permissions

As part of the io2 migration, we must ensure all directories are
explicitly *Opened* instead of using common *Connect* operations, since
the latter does not use any flags/rights. Because of this, when a
directory is connected to like a service, the connection lacks any
rights.

The Vulkan loader callbacks that open directories and connect to
services do not take any flag arguments, so we need to infer what the
target is based on the path. As all of these paths have well known
formats, so we make two assumptions:

  1. Paths such as `/loader-gpu-devices/class/gpu/001` should be
     connected to as a service (i.e. to the underlying device
     protocol).
  2. The `/loader-gpu-devices` directory should be opened as a
     directory.
  3. All other class paths that don't point to a particular device
     instance, such `/loader-gpu-devices/class/gpu`, should be opened as
     directories.

Opening directories with PERM_READABLE will be required to enumerate
child entries of these paths.

This only works right now as in io1, many operations - like directory
enumeration - were unprivileged. In order to start enforcing the new io2
rights model, we need to require that callers opening directories (or
other node types) explicitly set the flags/rights they want.
