[wasi-bindgen] Do not use serde-serialize

[sgirones]

wasi-bindgen's serde-serialize feature has been deprecated in favour of the serde-wasm-bindgen crate. See rustwasm/wasm-bindgen#3031 for more context, but in SurrealDB's case, it causes a dependency cycle when I try to add certain dependencies:

error: cyclic package dependency: package `getrandom v0.2.9` depends on itself. Cycle:
package `getrandom v0.2.9`

I checked all SurrealDB dependencies and they don't include the serde-serialize feature. Except for this one.

I was expecting cargo build or cargo test to fail, but they succeeded, so I assume the feature was not being used.
