docs: add deprecation message to td-tools

[danielpeintner]

What about https://github.com/eclipse-thingweb/node-wot/blob/master/packages/td-tools/src/thing-description.ts

It will continue to live in core, right?

Yes, but I would deprecate it and move it (or refactor) in one single PR.

Shall I deprecate each export like

node-wot/packages/td-tools/src/thing-description.ts

Line 26 in 15c5af7

export default class Thing implements TDT.ThingDescription {

node-wot/packages/td-tools/src/thing-description.ts

Line 62 in 15c5af7

export class Form implements TDT.FormElementBase {

etc in this PR. IF we do so we get warnings everywhere.

OR I would do it once we completely remove the entire td-tools package. That's what I would do.
I hope that matches with you...

What I meant was to move on with this PR and in other PR tackle the refactoring of duplicating thing-descriptio.ts to core package and deprecate the code in td-tools package. If we follow this approach we should not get any warning (once all the imports will be updated to use core instead of td-tools).
