  1. lib: make sure globals can be loaded after globalThis is freezed

    Since we made some of the globals lazily loaded to reduce startup
    overhead, and tried to update then as data properties once loaded,
    the lazily-loaded globals can no longer be loaded once globalThis
    is freezed. Fix this by not attempting to overwrite the property
    on loading these globals (so the property descriptors won't be
    spec-compliant in this case, but at least it's a good compromise
    between breakages and startup overhead).
    
    Note that certain globals that come from undici are still broken
    because undici attempts to define a global dispatcher symbol
    on globalThis. This is reflected in the test.
