feat(wasm): enable wasm32-unknown-unknown compilation of query connectors, query core, and request handlers

[jkomyno]

Proceeding with the work started in #4119, this PR enables compiling every local dependency up to request-handlers to WebAssembly (wasm32-uknown-unknown).

cd query-engine/request-handlers
cargo build --target wasm32-unknown-unknown --no-default-features

• In the prisma-models crate, we removed cuid from the wasm_generator feature flag, so that it won't be compiled (as it depends on hostname, which is not available in WebAssembly).
• For crates that indirectly depends on getrandom, we added the js feature flag to make it Wasm-compatible.
• For query core, query connector, and request handler crates, we added the native-connectors feature flag for enabling native (e.g., darwin-arm64) compilation.
• To avoid runtime errors in Wasm with std::time::Instant (which is not supported in every Wasm interpreter, e.g., in browsers), we provide a shim (instant).
