[Windowing] Fix regression for resolution label

[enen92]

Description

This fixes a regression caused by #23259 on platforms such as Linux and Android. We were using the resolution id as the label but it turns out on those platforms the id is already being used for other purposes, see #23259 (comment)

Hence in this PR we introduce a label property we are free to set from the windowing system for UI display purposes (e.g. when we select the resolution in the display settings) that takes precedence over the label that is created with the resolution internal properties (width, height, etc). We still match setting selection by ID but decouple the label from the id.

Motivation and context

Regression fix, restore same functionality as before.

How has this been tested?

Runtime tested in MacOS (source of the feature) and tested by @joseluismarti on other platforms
