Run object_store tests (on CI) with WASM build/runtime

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

• Part of ObjectStore WASM32 Support #6818

As we improve the story for using object_store with WASM we currently check that the code compiles with WASM, but have no coverage for actually running tests iina. WASM runtime to verify behavior. For example, as @XiangpengHao points out we have no way to verify support for files larger than 4GB (where WASM's 32-bit usize can be a problem):

• Use u64 range instead of usize, for better wasm32 support #6961

Describe the solution you'd like
I would like to run all relevant tests from object_store on a wasm runtime to ensure they actually run

Describe alternatives you've considered
I don't really know much about how this works, but I can imagine potentially using this crate:

https://github.com/bytecodealliance/wasmtime

Somehow to run the generated wasm

Additional context

@Xuanwo provided an example of how they do it in opendal: https://github.com/apache/opendal/blob/781682cc05b31d1f12f91fb7568a868f038c4d3b/.github/workflows/test_edge.yml#L62-L107

Thanks for the review @alamb , I agree with the rationale but unfortunately we don't yet have the infra to test wasm32 yet. We currently only build on wasm32, but there's no runner that can actually execute the webassembly

OpenDAL has an edge test for this; it's worth taking a look.
