Support MoltenVK

[zvasya]

Fixed loading of the "__Internal" library for iOS, iOS Simulator and MacCatalyst using the GetMainProgramHandle method from Net7.0.
And add package with MoltenVK libraries

Working examples can be found here: https://github.com/zvasya/VulkanExample

Updated packages are in the LocalPackages folder.

This is an amazing contribution I wasn't expecting to see given the state of our iOS support! Thank you so much! There's a few comments mostly relating to process and deployment, and a couple of code comments. Hopefully shouldn't take too much time, again thank you so much for your work here.

This is awesome! Please keep it coming, super excited to get Silk.NET.Vulkan working on iOS out of the box.

Good to go after this, thank you so much for your work!

I'm probably missing context here - I'm not really surprised that this works, but I'd appreciate if the relevant context is added here or even better the new attribute has some comment to explain why it's necessary.

(Using __Internal works fine for Sdl, right? Why is the attribute not necessary there?)

We discuss this with Perksey at https://discord.com/channels/521092042781229087/607634593201520651/1149730272754020384

In two words:
If I don't add this attribute, the generated file will contain an extra #endif. This is because #if is a trivia in the attributes that are being removed. And #endif is the leading trivia modifier.

And without this condition there is compiler (linking) error for Mac Release. Same error would be if add Silk.Net.SDL package to Mac project.
