Add functionality to the Crypto Module to create P12 certs containing…

[StefanMaron]

Summary

• Added a new dotnet wrapper to expose X509Certificate2.CreateFromPem
• Added new functions on X509Certificate2 and on RSA Codeunits

I did not yet create any tests for this, since I am not sure how I can test this and whether it needs testing since its essentially just wrapping dotnet functions.

I am not sure how you want to handle the custom dotnet library. I have included the code I created for testing here. If you want to to move/change anything, just let me know

Work Item(s)

Fixes #2516

After a lengthy discussion with @StefanMaron about the scenario, I've fiddled around with DotNet objects to find a way to achieve this without a custom .Net assembly. And I found a way that works.

Part of it uses the X509Certificate2(Byte[], string) constructor, which is known as dangerous because it allegedly creates temporary files and doesn't clean up afterward. Used incorrectly, it could potentially lead to disk overload. Therefore, I would recommend using this as a temporary solution and still plan for support of Span<T> and ReadOnlySpan<T> in AL code.

I'll discuss with @StefanMaron the code next week so he can change the PR accordingly (if he agrees with what I found).
