AssetCompiler hanged on rebuild with GraphicsApi change

Release Type: GitHub

Version: master

Platform(s): N/A

Describe the bug
I've built a project targeting Linux with the default Stride.sln build - so AssetCompiler ran with D3D11, next I recompiled Stride runtime packages with /p:StrideGraphicsApiDependentBuildAll=true, modified target project to use Vulkan and in VS did Rebuild - the asset compiler ran and then hang - I killed it after about an hour of waiting.

To Reproduce
I haven't had time to repro it again, look above for how I got here and below for when the log stopped.

Expected behavior
Asset compiler successfully completes after rebuild with GraphicsApi change

Additional context
After encountering the issue I have cleared the asset cache from obj/ and Build succeeded.

Start at the AssetCompiler entry point and compare the logged rebuild behavior when switching from D3D11 to Vulkan with the build settings change messages. Use the reproduction sequence and the paths under obj/ as investigation context, then verify that a rebuild completes without hanging and that clearing the asset cache is no longer required.
