PLATIR-45069: Add theme overrides for AEP Presentables

[prudrabhat]

Description

Currently UIService components are built to inherit the current activity's theme to maintain the app's styling. While this works for most cases, background is one the items where inheriting the parent theme as is does not work well, as this property applies to the view background for all views within an activity - covering the draggable floating button area, covering the in-app message background window etc.

This PR attempts to solve the problem by creating a copy of the current app theme and overriding specific attributes with values that are needed.
