Closes #31192
Adds support for creating vanilla (non-contextified) V8 contexts via vm.createContext(vm.constants.DONT_CONTEXTIFY). This creates a context without property interceptors, where globalThis is reference-equal to the returned object and Object.freeze(globalThis) works correctly.
This is needed by libraries like jsdom that require contexts without interceptor overhead. The feature was added in Node.js v22.8.0.
Enables node_compat test: test-vm-context-dont-contextify.js
