rbalsleyMSFT 8229aa73fe Add BITS transfer priority configuration support
Introduces a new parameter to control BITS download priority across the build system and UI, allowing users to optimize transfer speeds when needed.

The feature adds a priority selector to the UI with four options (Foreground, High, Normal, Low) and propagates the selection through the build script and common modules. Priority can be set via UI, command-line parameter, or environment variable, with Normal as the default.

Updates the BITS transfer retry logic to respect the configured priority instead of hardcoding Normal priority, and fixes minor code formatting inconsistencies.

.SYNOPSIS
Provides a collection of shared helper functions for manipulating WPF UI controls, handling asynchronous updates, and managing common UI interactions.
.DESCRIPTION
This module contains a variety of reusable functions designed to support the FFU Builder UI. It includes utilities for managing ListView controls, such as sorting, reordering items, and handling 'Select All' functionality. It also provides thread-safe mechanisms for updating the UI from background tasks, wrappers for modern and classic file/folder dialogs, and generic functions for clearing UI content. These shared functions help to reduce code duplication and ensure consistent behavior across different parts of the application.
