fix: select text on auto focus for TextInput

[kunalchavhan]

Summary:

Fixes: #43413

This pull request addresses an issue on Android where the text selection was not working when both selectTextOnFocus and autoFocus were set to true on TextInput. ReactTextInputManager was calling setSelectAllOnFocus on ReactEditText before its onLayout is called causing text selection to not work on auto focus.

Changes Made

• Added logic to wait for the ReactEditText view's layout to be drawn before attempting to select the text. On the first layout pass, the code now explicitly calls selectAll() to select the text.
• Implemented a check to ensure selectAll() is only called during the first layout pass, avoiding unnecessary calls on subsequent layout passes.

Impact This change ensures that text selection is properly triggered when selectTextOnFocus and autoFocus are both enabled, improving the user experience and making text input behavior consistent and reliable.

@cortinico Can you please help in reviewing this PR? Thank you for your time.

[kunalchavhan]

@kunalchavhan thanks for sending this over

Can I ask you to add a sample for RN-Tester (the one you're showing in your screenshots)

Sure, will add it.

[kunalchavhan]

@cortinico I have added sample in RN-Tester as you suggested. Took the liberty to combine autoFocus and selectTextOnFocus in one sample instead creating separate one to avoid focus conflict hope this is fine.
