feat: make svgView getter public (#2583)

# Summary

This PR reverts #2555, as `RenderableView.hitTest()` can be replaced by
`SvgView.reactTagForTouch()`, which is already `public`.

This PR also changes the `package-private` `getSvgView()` method of
`VirtualView` to `public`.
This change has been made to handle hit detection of transformed
`VirtualView`s, as `RenderableView`'s `hitTest()` doesn't take
transformations into account, while `SvgView`'s `reactTagForTouch()`
does.

Making `getSvgView()` public is necessary for integrating RNSVG support
into RNGH. More details
[here](https://github.com/software-mansion/react-native-gesture-handler/pull/3242/).

## Test Plan

Run the example from the RNGH - RNSVG [integration
PR](https://github.com/software-mansion/react-native-gesture-handler/pull/3242/).
