Add PVM versioning support and update build script

- Introduced a new section in `Cargo.toml` for PVM versioning, setting the current version to "0.0.2". - Updated `build.rs` to read the PVM version from the environment or `Cargo.toml`, enhancing build configuration. - Modified `version.rs` to include the PVM version in the output format for better clarity in version reporting.
