[Android] Using adjustsFontSizeToFit=true sometimes causes font size to be too small.

Description

Even when there is no need to shrink the font, there is sometimes a difference in the font sized used when adjustsFontSizeToFit is true vs. when it is false (or not included as a prop on a <Text> component). In other words, the font size is reduced when it should not be. This problem was introduced by the fix for #54715.

Specific font sizes needed to show this bug vary depending on the dp-to-font ratio of the test system or emulator, which points to rounding as the root cause of this bug.

Steps to reproduce

1. Use two components, one with adjustsFontSizeToFit={true} and one without.
2. Experiment with different fontSize values until you find one or more where the rendered size differs (even though there is no need to reduce the font to accommodate the text).

The provided reproducer demonstrates the problem.

MANDATORY Reproducer

Screenshots and Videos

Notice the text rendering differences for the following font sizes: 10, 11, 18, 22.

Beginne mit dem obligatorischen Reproducer in RNTesterPlayground.js und vergleiche das Android-Rendering für Text-Komponenten mit und ohne adjustsFontSizeToFit bei den gemeldeten Schriftgrößen. Verfolge die Android-Implementierung dieser Prop und konzentriere dich dabei auf das durch #54715 eingeführte Rundungsverhalten. Als erledigt gilt die Aufgabe, wenn die gerenderten Schriftgrößen gleich sind, sofern kein Verkleinern erforderlich ist, einschließlich der Fälle im Reproducer.
