rust: add definitions for vmstate

Add a new qemu_api module, `vmstate`. Declare a bunch of Rust
macros declared that are equivalent in spirit to the C macros in
include/migration/vmstate.h.

For example the Rust of equivalent of the C macro:

  VMSTATE_UINT32(field_name, struct_name)

is:

  vmstate_uint32!(field_name, StructName)

This breathtaking development will allow us to reach feature parity between
the Rust and C pl011 implementations.
