Add: support for arguments reading pattern in typescript definition.

[sasensi]

Description

Introduces hardcoded generic types in the typescript definition template that
are used to support arguments reading pattern (that allows a method to accept
either a Point instance or an array of number or an object...).

Maybe this can find a place in JSDoc at some point but I think that this does the job for now.

• Relates to Some missing types of build-in typescript definition file. #1659

Checklist

• New tests added or existing tests modified to cover all changes
• Code conforms with the JSHint rules (npm run jshint passes)

@sasensi what is the status on this PR? I really need this ;) Typescript types are basically useless if you use string colors or array points.

@lehni can we merge this?

I'm so sorry for never looking into this. The code looks good! It only adds the versions that read from objects, while in JS you can also do <METHOD_NAME>(x, y) instead of <METHOD_NAME>({ x, y }) where pointLike values are read. With this change, only <METHOD_NAME>([x, y]) will be supported.
