  [clang][ssaf] Remove VFS support from SerializationFormat (#180891)

This change removes support for `VFS` in `SerializationFormat`,
introduced in https://github.com/llvm/llvm-project/pull/179516/. `VFS`
only provides a virtual input backend and its matched pair,
`VirtualOutputBackend`, does not provide support for an
`InMemoryOutputBackend`. There was an attempt from our end to implement
this support in https://github.com/llvm/llvm-project/pull/179515 but it
did not succeed. Supporting virtual reads but not virtual writes makes
the SerializationFormat APIs asymmetric. So we have decided to remove
`VFS` support altogether.
