[PLATIR-41103] Added dialog for correct screen reader case

[navratan-soni]

Added dialog in case of UI take over for IAM , for making screen reader only read the content of IAM and not the UI beneath it.

Description

Previously we were adding IAM directly in the activity UI, which, for screen readers, was just another content on the screen. So screen reader always read from top to bottom, regardless of IAM was showing or not.
To make IAM getting read only while it is showing, we need to put it in a component which is a layer above the existing UI. So we chose to go with dialog with this. Also we have kept this behavior only in case of UI takeover is true, else it will block the direct interaction to UI beneath it.

Tested for all the existing templates.
Ensured that non-ui take over case also remains the same
