FastTextRenderer crashes on Vulkan

Release Type: GitHub

Version: master and 4.2.0.2381

Platform(s): Windows Vulkan

Describe the bug
When creating the GameProfiler it uses the FastTextRenderer which causes a crash due to trying to use WriteDiscard.

To Reproduce
Steps to reproduce the behavior:

1. Add default GameProfiler class to an empty project
2. Set the Graphics API to Vulkan in the csproj
3. watch the shaders compile
4. crash when running

Expected behavior
It should either:

• add an error for Vulkan in the GameProfiler class that explains it as incompatible
• Use an alternative to FastTextRenderer for Vulkan

Start with Stride.Engine/Profiling/GameProfilingSystem.cs around line 391 and follow the FastTextRenderer.End and CommandList.MapSubresource calls shown in the stack trace. Reproduce the crash with the default GameProfiler in an empty Windows Vulkan project, then determine whether the completed fix should provide a Vulkan incompatibility error or avoid FastTextRenderer; verify that running no longer crashes.
