Wasm Tests

We expect to reuse the tests for Rspack wasm target as many as possible and we have managed to do it partially. Currently wasm tests should be run with an environment variable WASM=1 under the following limitations:

1. Node 20 is required, which is consistent with the Node version in StackBlitz.
2. Set maxWorkers to 1, maxConcurrency to 1 and disable concurrent mode to avoid flaky failures.
3. forceExit is needed.

Also check all the skipped testcases with !process.env.WASM in test.filter.jss and the skipped testsuits in rstest.config.tss. They are divided into two categories:

1. Skip due to lacks of api support, such as tests related to swc wasm plugins, pnp and profiling. We skip them to avoid obsolete snapshot errors.
2. Skip temporarily and should be investigate in the future. There could be something wrong with test harness and rspack wasm itself. Since it could be time-consuming to figure out all of them so in this stage we use the wasm test ci to avoid the regression rather than improve its stability.
