fix(common): use 64-bit API on Windows to get file sizes

[HoraceBianchon]

For files with a size bigger than 2GB (32bit unsigned integer's max value) calculation based on the "::stat" function doesn't work correctly on the Windows operation systems.
I replaced the "::stat" function with "::stat64". For more details on the "::stat", please see link below

I, mistakenly, committed with my corporate email.
And, now, I can't pass that signing.
