Description of your changes

As described in #1058 the decorator implementation was affected by an issue that prevented the decorated method/class to access other class members as the value of this was passed incorrectly.

This PR aims at fixing the issue, creating an unit test case, making minimal changes to the function in the e2e test to verify the change, and update docstrings/docs.

A long form explanation of the issue can be found at #1055, when merged this PR will close #1058.

One small nit.

Also, similar to #1055, we should also update the examples/cdk/src/*.Decorator.ts files. They still don't use .bind() method. We can have this in another PR if you prefer (then I'll approve this).

[ijemmy]

Approved.

Discussed with @dreamorosi , we'll go with this to push the fix first.

The example will be updated in a separated PR.
