Text: Fix selectable prop mapping (was isSelectable) for Fabric - ensure correct macro conversion

[iamAbhi-916]

Summary:

for IOS and React native windows we can observe that the macro conversion is incorrect in ParagraphProps particularly for selectable prop.

current conversion

case ([]() constexpr -> RawPropsPropNameHash {   return facebook::react::fnv1a("isSelectable");  }()): fromRawValue(context, value, isSelectable, defaults.isSelectable); return;

issue is that isSelectable is not the raw prop therefore JS to native flow for the prop is not correct .
(Note : this works for Android as @ReactProp(name = "selectable"):

react-native/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/views/text/ReactTextAnchorViewManager.kt

Lines 97 to 100 in bbc1e12

	@ReactProp(name = "selectable")
	public fun setSelectable(view: ReactTextView, isSelectable: Boolean) {
	view.setTextIsSelectable(isSelectable)
	}

)

after fix

case ([]() constexpr -> RawPropsPropNameHash {   return facebook::react::fnv1a("selectable");  }()): fromRawValue(context, value, selectable, defaults.selectable); return;

Current implementation selectable prop is not working for IOS and React native windows as the macro conversion is incorrect in ParagraphProps particularly for selectable prop.

Changelog:

Updated ParagraphProps declaration .h/.cpp file for selectable raw prop and then refactoring their respective implementations
all places required .

Test Plan:

Tested on react native windows playground

Sample code

export default class Bootstrap extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.header}>Selectable vs Non-Selectable Text</Text>

        <Text selectable={true} style={styles.text}>
          ✅ This text is selectable. You can long-press and copy it.
        </Text>

        <Text selectable={false} style={styles.text}>
          ❌ This text is not selectable. You cannot copy it.
        </Text>
      </View>
    );
  }
}

before fix debug output , native unaware of selectable prop values from JS

ReactNative ['Samples\text'] (info): ''[Text.js] NativeText _selectable:', true'
ReactNative ['Samples\text'] (info): ''[Text.js] NativeText _selectable:', false'
[ParagraphComponentView] updateProps - old isSelectable: 0, new isSelectable: 0
[ParagraphComponentView] DrawText - isSelectable: 0
[ParagraphComponentView] DrawText - selection logic would be DISABLED here.
[ParagraphComponentView] updateProps - old isSelectable: 0, new isSelectable: 0
[ParagraphComponentView] DrawText - isSelectable: 0
[ParagraphComponentView] DrawText - selection logic would be DISABLED here.
[ParagraphComponentView] updateProps - old isSelectable: 0, new isSelectable: 0
[ParagraphComponentView] DrawText - isSelectable: 0
[ParagraphComponentView] DrawText - selection logic would be DISABLED here.

after fix debug output , native picks up selectable prop values from JS correctly

ReactNative ['Samples\text'] (info): ''[Text.js] NativeText _selectable:', true'
ReactNative ['Samples\text'] (info): ''[Text.js] NativeText _selectable:', false'
[ParagraphComponentView] updateProps - old selectable: 0, new selectable: 0
[ParagraphComponentView] DrawText - selectable: 0
[ParagraphComponentView] DrawText - selection logic would be DISABLED here.
[ParagraphComponentView] updateProps - old selectable: 0, new selectable: 1
[ParagraphComponentView] DrawText - selectable: 1
[ParagraphComponentView] DrawText - selection logic would be enabled here.
[ParagraphComponentView] updateProps - old selectable: 0, new selectable: 0
[ParagraphComponentView] DrawText - selectable: 0
[ParagraphComponentView] DrawText - selection logic would be DISABLED here.
