Typescript[all components]: re-write components to Typescript

[ilhan007]

Feature Request Description

As a typescript developer,
I would like to
make use of TS definitions for the UI5 Web Components project,
so I can
see easily see the available APIs, without constantly checking the API reference,
benefit from static code checks, use decorators for component metadata.

Proposed solution

Re-write all components in Typescripts.
