Description

Calling "FStaticMeshCompiler::FinishCompilation" on multiple assets simultaneously can cause a hang.

Also tested on //UE5/Release-5.5, CL: 36784631

Steps to Reproduce

1. Download the Licensee's test project, and compile. (See addl info URL)
2. Launch the editor with the command-line argument "-run=ValidationCommandlet"
3. Observe the stall.
If it does not stall, try again. If it is difficult to reproduce, try duplicating the static meshes found under /Game/ a few times.
4. Through Visual Studio, pause execution, and see that all threads are sleeping.
