RFR: 8205067: Resizing window with TextField hides text value [v2]

[Karthik P K]

> Because of a missing conditional check in the `updateTextPos()`,  the `textTranslateX` value was not getting updated when TextField size was changed as a result of resizing window.
> 
> Updated the CENTER and LEFT cases in the `updateTextPos()` method to fix the issue.
> 
> The fix can be validated using MonkeyTester.
> Steps to select TextField option in Monkey Tester.
> 
> - Open the MonkeyTester app and select TextField from the left option pane.
> - Select Long from Text selection option and TOP_LEFT from Alignment dropdown.
> - After above step, follow the steps given in the bug to validate the fix in monkey tester.
