refactor(ui5-link): wrap text by default

[hinzzx]

The text of ui5-link now wraps by default.

BREAKING CHANGE: wrapping-type property default value has changed from None to Normal. Before:

<ui5-link>some very very very long link</ui5-link> <!-- would truncate the text if there is not enough space -->

Now:

<ui5-link>some very very very long link</ui5-link> <!-- would let the text wrap if there is not enough space -->
