Add constructor to tls.Certificate

[rogierschouten]

Is your feature request related to a problem? Please describe.
I would like to parse an x509 certificate to be able to show its fingerprint to the user. Most NPM packages that parse certificates have failing npm install on Windows due to build issues w.r.t. different versions of OpenSSL.

Describe the solution you'd like
The node TLS module already has a Certificate interface that contains everything I need. I just need it to be a class so that I can also load a given certificate string into it instead of just getting this interface from the TLS connection.

It would seem that the node implementation already has certificate parsing available internally.

Describe alternatives you've considered
NPM packages x509 (doesn't build), x509.js (contains crypto library in github repo), x509-ts (un-finished), various forks of x509

This was requested recently in #29181 so I'm going to go ahead and close this out as a duplicate of that other issue.
