fix(packages/react-native): pass testID to the rendered Svg element (#4881)

The Icon component destructured `testID` out of its props and re-emitted it as
`data-testid`, which is a web attribute. react-native-svg only forwards `testID`
to the native view (see extractProps) and drops `data-testid`, so
`<Icon testID="my-icon" />` rendered an element that no React Native test query
or UI automation tool can find. `LucideProps` extends `SvgProps`, so the prop
type checks and the failure is silent.

v0 spread `testID` straight onto `Svg`, so this is a regression for React Native
consumers. An explicitly passed `data-testid` still reaches the element through
the remaining props, so nothing is lost for react-native-web users.

The react-native-svg test mock now maps `testID` onto `data-testid`, so the
DOM based test suite identifies elements the way React Native does. Every
existing `testID` test fails against the previous behaviour.
