Add version to quickjs provider wasm file

[jianghong]

We want to expose the version set in the Javy Core crate's Cargo.toml as part of the javy_quickjs_provider.wasm file so third-party developers using the module can inspect the version of the module and confirm it is the version they are expecting.

An ideal implementation would encode the major, minor, and patch versions inside a single i64 exported by the Wasm module. Less ideally would be three separate exports for major, minor, and patch versions. And if that approach doesn't work, then use a custom section.

Using an export of a single i64 is ideal because it minimizes code size and is easy for consuming code to retrieve (that is, they do not need to use wasmparser). We should be able to use a single i64 by reserving different ranges of bits in the i64 for different parts of the version and use bit shifting to encode the three components of the version and on the calling side, bit shifting to decode the three parts of the version.
