PLATIR-45069: Add theme overrides for Floating button 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 solves the problem by creating a copy of the current app theme and overriding specific attributes with values that are needed. This override is applied only for FloatingButton presentables for now to limit the scope. We can look into adding this approach (simply invoking getThemedContext()) to other presentables if there are more requests.

Motivation and Context

How Has This Been Tested?

• Instrumentation tests
• Manual tests
  • Added a non transparent android:background value for the testapp (tested both Theme.AppCompat.* and android:Theme.Material) and ensure that the floating button still shows up with a transparent background draggable area.
  • Trigger non floating button presentables in combination with floating button to ensure that the override is only applied to floating buttons.
