test: skip SEA tests when SEA generation fails

In the SEA tests, if any of these steps fail:

1. Copy the executable
2. Inject the SEA blob
3. Signing the SEA

We skip the test because the error likely comes from the system or
postject and is not something the Node.js core can fix. We only leave
an exception for a basic test that test injecting empty files as
SEA to ensure the workflow is working (but we still skip if copying
fails or signing fails on Windows).

 Skip the rest of the tests if single executable applications are not supported

-### `injectAndCodeSign(targetExecutable, resource)`
+### `generateSEA(targetExecutable, sourceExecutable, seaBlob, verifyWorkflow)`
 
-Uses Postect to inject the contents of the file at the path `resource` into
-the target executable file at the path `targetExecutable` and ultimately code
-sign the final binary.
+Copy `sourceExecutable` to `targetExecutable`, use postject to inject `seaBlob`
+into `targetExecutable` and sign it if necessary.
+
+If `verifyWorkflow` is false (default) and any of the steps fails, it skips the tests.
+Otherwise, an error is thrown. On Windows, if the failure happens at signing,
+the stderr string is attached to `error.stderr` in the `error` being thrown.
