Add SVG support for Card Cover

**Is your feature request related to a problem? Please describe.**
We can not add an SVG as Card Cover: https://callstack.github.io/react-native-paper/docs/components/Card/CardCover.

Event with this library it does not works: https://www.npmjs.com/package/react-native-svg
It gives this error: `TypeError: cyclical structure in JSON object`

**Describe the solution you'd like**
It will be great to support with a props names SVG like:

` }} />`
