fix(audio-info): crash when device name contains special characters

[ReenigneArcher]

Description

This PR fixes audio-info (and maybe dxgi-info) from crashing when special characters exist in the device names or any properties.

Additionally, the formatting was slightly modified for dxgi-info. The output line was previously included even if the device had no output devices attached. The location of the empty line was also changed.

To complete the fix I moved the utf conversion functions out of misc.cpp/h in order to simplify inclusion of these functions in the tool binaries. This is still somewhat more complex than it needs to be due to having to include logging, which requires libdisplaydevice and FFmpeg (libavutil).

Finally, I corrected some IDE and Sonar complaints such as:

• case for Windows.h include was wrong
• used c-style cast instead of c++ style
• added const when possible
• added a default case for a switch
• some variables could be initialized inside the if condition

Pull Request Overview

This PR fixes crashes in audio-info and dxgi-info tools when device names contain special characters by implementing proper UTF conversion utilities. The changes include creating a new utf_utils namespace for safer UTF conversion, migrating away from the deprecated Boost.Locale library, and improving code quality with modern C++ best practices.

Key changes:

• Adds new utf_utils namespace with UTF conversion functions to replace the previous platform-specific implementations
• Migrates audio-info and dxgi-info tools to use standardized UTF-8 output instead of wide character streams
• Consolidates UTF conversion logic from multiple Windows platform files into a single utility module

Incorrect property access. The line uses device_friendly_name.prop.pwszVal but the property should be accessed as device_friendly_name.prop.pszVal based on the PROPVARIANT structure for string values.

Suggested change
