Fixed android bounding box (#25836)

Summary:
This PR fixes #19637.

Summary of the issue: on Android, transformed touchables have press issues because the touchable's measurements are incorrect in the release phase. `UIManager.measure()` returns an incorrect size and position as explained [here](#19637 (comment))

This is easily seen with the inspector :

**Screenshot of a { scale: 2 } transform**
The real view (scaled) is in pink, the incorrect touchable area is in blue.

**Screenshot of a { rotateZ: "-45deg" } transform**
The real view (rotated) is in pink, the incorrect touchable area is in blue.

## Changelog

[Android] [Fixed] - Fix UIManager.measure()
Pull Request resolved: #25836

Test Plan:
Android now produces the same results as iOS as seen on these screenshots
