fix: generate correct worker expression with trusted types

[LingyuCoder]

Summary

fix #8134

When output.trustedTypes is set, the new Worker(new URL(xxx)) should be compiled to new Worker(__webpack_reuqire__.tu(new URL(xxx))), but now it is compiled to new Worker(new URL(__webpack_require__.tu(xxx)))

The webpack-test/configCases/trusted-types/web-worker case can pass because the mock environment does not have trustedTypes.createPolicy so that the __webpack_require__.tu(xxx) will return xxx directly.
