Blazor AOT performance vs ReadyToRun

[lbargaoanu]

I have this project. It uses Roslyn to compile some code.
A lot of time is spent JIT-ing, so AOT compiling makes sense. For the console application, I get a significant benefit with ReadyToRun.
For the Blazor app compiled with AOT, I get no improvement. As far as I can tell, it is indeed compiled AOT :)

I moved this over to #54265 for tracking purposes.
