[type:refactor] replace inactive wasmtime-java with chicory pure-Java WASM runtime

[eye-gu]

fix #6353

wasmtime-java is no longer actively maintained — no recent releases or commits. As a native-library-dependent runtime, it also introduces platform coupling and deployment friction. This PR replaces it with Chicory, an actively maintained pure-Java WASM runtime (Apache 2.0), eliminating both the maintenance risk and native dependencies.

• Runtime compilation: Chicory's compiler module uses MachineFactoryCompiler to translate WASM bytecode into JVM bytecode at module load time, significantly improving execution performance over interpreter-only mode. Falls back gracefully to the interpreter if compilation is unavailable.
• TinyGo support: Added internal test helper wasmabi Go package (src/test only) to simplify
  wasm test module communication with the Java host, enabling Go-based WASM plugin development alongside existing Rust support. All test suites now verify both Go and Rust .wasm outputs.

Make sure that:

• You have read the contribution guidelines.
• You submit test cases (unit or integration tests) that back your changes.
• Your local test passed ./mvnw clean install -Dmaven.javadoc.skip=true.

Pull request overview

This PR refactors ShenYu’s WASM plugin runtime by replacing the inactive, native-dependent wasmtime-java integration with the pure-Java Chicory runtime, and extends the test suite to execute real .wasm artifacts produced by both Rust and TinyGo (Go) to validate the shared-memory ABI end-to-end.

Changes:

• Replace wasmtime-java APIs with Chicory (ExportFunction, Store, Memory) across the WASM loader and WASM plugin/handler abstractions.
• Add TinyGo “wasmabi” helper package plus multiple TinyGo test WASM modules and integrate them into JUnit tests to validate real WASM execution on CI.
• Update build/dependency metadata and release license docs to remove wasmtime artifacts and include Chicory artifacts.

• This LICENSE file omits the Apache 2.0 appendix while still containing text that references it ("an example is provided in the Appendix below"). That makes the license text internally inconsistent and may cause release compliance checks to fail; either include the full standard Apache 2.0 license text (including appendix) or remove/adjust references accordingly.
