Clip children extremely slow on Android

[felipejfc]

Tested versions

4.3 Stable

System information

Godot 4.3 Android ARM64

Issue description

A simple 2d Menu with some buttons with clip children enabled will have poor performance on Android phone. Even on good models. Testing on iOS I didn't observe the same.

Steps to reproduce

Create a button add a style like round corners, put either a label or a texture inside the button and make it clip children. See FPS drop by a lot.
