_MrtCoreUpToDateCheckInput recursively calls GetMrtPackagingOutputs during design-time builds.

Nobody has claimed this yet.

### Describe the bug

_MrtCoreUpToDateCheckInput target hooks into design-time builds via CollectUpToDateCheckInputDesignTime. This target has a DependsOnTargets on GetMrtPackagingOutputs which calls itself recursively calls on all transitive projects references.

In solution with lots of projects using WinAppSDK this results in a significant performance decrease for both project loading as well as design-time builds done by Visual Studio.

### Steps to reproduce the bug

N/A

### Expected behavior

The expected behavior for design-time builds and FUTDC (Fast Up To Date Check) is to only collect info for the current project.

### Screenshots

_No response_

### NuGet package version

Windows App SDK 1.3.2: 1.3.230602002

### Packaging type

Packaged (MSIX)

### Windows version

Windows 11 version 22H2 (22621, 2022 Update)

### IDE

Visual Studio 2022

### Additional context

_No response_

Read the _MrtCoreUpToDateCheckInput and CollectUpToDateCheckInputDesignTime target definitions, then trace their DependsOnTargets relationship to GetMrtPackagingOutputs. Verify completion by confirming that design-time builds and FUTDC collect data only for the current project without recursively invoking packaging outputs for transitive project references.
