Henry Jiang 412d6941e3 [VFS] Guard against null key/value nodes when parsing YAML overlay (#190506) ...

When a VFS overlay YAML file contains malformed content such as tabs,
the YAML parser can produce KeyValueNode entries where `getKey` returns
nullptr. The VFS overlay parser then passes the nullptr to
`parseScalarString`, which then calls dyn_cast.

Switch to `dyn_cast_if_present` for the above callsites and a few more.
