feat: Privacy Manifest And xcframework Sign

[MatteoBatti]

• OpenSSL utilizes stat, fstat and lstat, which must be declared in the PrivacyInfo.xcprivacy files under the category NSPrivacyAccessedAPICategoryFileTimestamp

• Starting from May 1st, xcframeworks must also be signed. I've added a parameter in the create-frameworks.sh script where you can provide your apple signing identity.

OpenSSL utilizes stat, fstat and lstat

for clarity, do you happen to have a pointer where it is used by the library?

I applied xcframework codesign on the main branch, and discarded changes to the privacy manifest file from this PR as discussed in https://github.com/krzyzanowskim/OpenSSL/pull/202#discussion_r1564916651

thank you for bringing it to my attention. update with the changes will be released soon.
