Support .Net 8 preview 3 unified artifacts

Bugs

WiX 4.0

4.0.0+8c757c0f

Visual Studio 2022 v17.6.0 Preview 3

Heatwave 1.0.1

.Net 8.0.0-preview.3.23174.8

.Net 8 preview 3 introduced a unified project artifact directory enabled by specifying

<UseArtifactsOutput>true</UseArtifactsOutput>

in Directory.Build.props

Building an installer with this property enabled with WiX 4 results in a package generated in the directory of the wixproj project file while all other projects respect the new option.

This is not terrible, but I'd request that WiX 5 follows the unified output convention introduced in the .Net 8 SDK
