Closes #4357 On Windows, `chmod` can only change read and write permissions (https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/chmod-wchmod?view=msvc-170). It doesn't implement distinct permissions among group, owner, or others. Changes in this PR also enables `node:fs`’ `chmod` on Windows and fixes the `prefer-primordials` lint rule #24236.
