fix: setting invMatrix during setTransforms for iOS (#2810)

# Summary
Fixes: #2809 

1. Fix `setTransform` to correctly update `_invmatrix` for hit testing.

Previously, the `setTransforms` setter in `RNSVGNode` updated the
`_matrix` property but did not recompute the `_invmatrix`.
As a result, hit testing on iOS could become inaccurate when transforms
were applied via Reanimated’s `animatedProps`, because the visual
transform `_matrix` and the cached inverse `_invmatrix` were out of
sync.
This PR modifies `setTransforms` to update `_matrix` through its setter
ensuring that `_invmatrix` is recomputed properly whenever the
transforms changes.

2. Remove unused `invTransform` from `VirtualView.java`.

## Test Plan

Run example from issue #2809
