[SDK-3870] Typescript Migration

[poovamraj]

Changes

We are migrating to Typescript to provide better developer experience. Things to consider in this PR are

• We have migrated all our source code to strict typescript migration (except tests and mocks)
• The folder webauth can be reviewed a little leniently as we will move it to native code in the current initiative

Testing

• This change adds unit test coverage
• This change has been tested on the latest version of the platform/language or why not

Nice work on migrating this to TypeScript 🚀

I left a couple of comments, but in general I think it's useful to revisit the amount of any's being used. There are situations where I think it's okay to keep any, but quite a bit (especially when it comes to option parameters) should probably better be typed.

Some any's could also be unknown, which in that case might something we want to consider using (I added a comment for an example on where I think it should be possible to use unknown).

@frederikprijck I have improved the amount of any used now. Above all now our authentication client methods will have type support. I have also implemented all the comments you have added. Thanks for the feedback 🙇 Do check this out when you have time

Added some comments, but I believe there are still some fundamental issues in ensuring TypeScript is useful here.
