Apple m1 support

[amircodota]

Hi, folks

Amir from tabnine here.

We have recently released support the new for Apple M1 processors.
This requires some changes on the plugin side too.

We've updated the how to write a plugin document.
We also implemented it in various other plugins, so you can check it out to get inspiration :-)

vscode
sublime
intellij
vim

Note that supporting m1 when the editor is run nativelyon arm is usually pretty straight forward. However, supporting a case where the editor is running on the Rosetta translator is a little more complex (see this).
