Make the Vector API an optional dependency of GraalWasm

GraalWasm now requires jdk.incubator.vector using "requires static". If
the jdk.incubator.vector was not provided, we fall back to our previous
implementation. This makes incubator warnings opt in.

   This aligns with the JS WebAssembly API and allows other members to be introduced on the module instance without potential name clashes.
   More information about these API changes and examples can be found in the [GraalWasm Polyglot API Migration Guide](docs/user/GraalWasmAPIMigration.md) and the [Readme](docs/user/README.md).
 * Implemented support for editing primitive values during debugging. Fixed several debugger-related issues.
-* The [SIMD](https://github.com/WebAssembly/simd) proposal is now implemented using the JDK's Vector API.
-  This improves peak performance when running WebAssembly code which makes heavy use of the new instructions in the SIMD proposal.
-  Since the Vector API is still incubating, you will see the following message when running GraalWasm on the JVM.
+* Added an implementation of the [SIMD](https://github.com/WebAssembly/simd) proposal using the JDK's Vector API. This improves peak performance when running WebAssembly code which makes heavy use of the new instructions in the SIMD proposal. This new implementation is always used in native image. On the JVM, it is opt-in and requires setting `--add-modules=jdk.incubator.vector`. Use of the incubating Vector API will result in the following error message being printed to stderr:
   ```
   WARNING: Using incubator modules: jdk.incubator.vector
    ```
