Keep ellipsizeMode when adjustsFontSizeToFit is set on Android

[conner1reimers]

Summary:

On Android, ReactTextView.updateView() clears the ellipsize location whenever adjustsFontSizeToFit is set. Text that still does not fit after shrinking is clipped instead of being truncated with the requested ellipsizeMode. iOS applies ellipsizeMode regardless of adjustsFontSizeToFit.

The original Android implementation cleared it deliberately to avoid incorrect ellipsizing while the text is being shrunk (#26389 (comment)). With #58492, Android now respects minimumFontScale, so shrinking can stop while the text is still too large.

This PR applies the ellipsize location when numberOfLines is set and the text still exceeds it at the minimum font size. TextLayoutManager.adjustSpannableFontToFit() now reports whether that is the case, and ReactTextView keeps the result for updateView(). Applying the ellipsize location unconditionally caused the last glyph of otherwise-fitting text to be clipped, since TextView lays text out slightly wider when an ellipsize is set than the fit loop measures without one.

This was split out of #58492.

Changelog:

[ANDROID] [FIXED] - Apply ellipsizeMode to text that still overflows with adjustsFontSizeToFit

Test Plan:

Unit tests

Added coverage for:

• Applying the ellipsize location while text still exceeds numberOfLines, and removing it once the text fits
• adjustSpannableFontToFit() returning the expected result when text fits, exceeds the allowed number of lines, or only exceeds the available height

./gradlew :packages:react-native:ReactAndroid:testDebugUnitTest --tests 'com.facebook.react.views.text.*'

All 48 com.facebook.react.views.text tests pass, including the new cases.

With #58492, the "Can limit how small the text becomes with minimumFontScale" line in the Android Text example stops at 50% of its font size. Before this change, the overflow is clipped; after, it ends in an ellipsis.
