[Sober7135]

Reason for this PR

#831 add VertexInfo for Rust binding.

What changes are included in this PR?

• Add Rust info module:
  • rust/src/info/mod.rs exports InfoVersion, VertexInfo, VertexInfoBuilder
  • rust/src/info/version.rs: InfoVersion::new(i32) wrapper over shared_ptr<const graphar::InfoVersion>
  • rust/src/info/vertex_info.rs: VertexInfo::{try_new,new} + builder API, labels & property-group accessors, and dump/save
• Extend C++ glue + FFI surface:
  • rust/src/graphar_rs.cc + rust/include/graphar_rs.h:
    • new_const_info_version
    • create_vertex_info (adds input validation with explicit error messages)
    • vertex_info_save / vertex_info_dump
    • property_vec_clone / property_group_vec_clone
  • rust/src/ffi.rs: expose the above APIs to Rust; derive Clone for SharedPropertyGroup
• Property utilities:
  • rust/src/property.rs: implement Clone for PropertyVec and PropertyGroupVector using the C++ clone helpers
• Dev dependency:
  • rust/Cargo.toml: add tempfile for filesystem-related unit tests
