[iOS, Mac, Windows] SearchBar CharacterSpacing property is not working as expected

[TamilarasanSF4853]

Description

The CharacterSpacing property of the SearchBar control does not behave consistently across platforms.

• On iOS and macOS: CharacterSpacing is not applied to either the search text or the placeholder text. Both are always rendered with the default spacing, regardless of the value set.

• On Windows: CharacterSpacing is applied to the search text but not to the placeholder text. The placeholder continues to display with default spacing.
