Fixes: #30538

Background

#18618 uses access instead of stat to implement fs.existsSync. Unfortunately, seems the two approaches both have some limitations at Windows:

Expected behavior of existsSync stat access
Invalid symlink false ✅
File without privileges true ✅

This PR adds a double check only at win32 platform to fix this issue.

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • tests and/or benchmarks are included
  • commit message follows commit guidelines

The change looks reasonable. Rubberstamp LGTM if the test fails without this change.
