Add support for filter element to babel-plugin-transform-react-native-svg

[adorum]

🚀 Feature Proposal

react-native-svg already supports some of filter elements e.g. Filter, FeColorMatrix, FeGaussianBlur,... (all listed here software-mansion/react-native-svg#2362),

Motivation

Would be fine to support svg filter in react-native apps in order to achieve e.g. shadows.

It would be great to add the Filter support. Currently, we get this when transforming SVGs with the filter attribute on react-svgr.com:
/* SVGR has dropped some elements not supported by react-native-svg: filter */

Even though, react-native-svg does indeed support them.
