Blazor WebAssembly AOT publiish output contains files that should not be published

[danroth27]

Repro steps:

• Install .NET 6 Preview 4 (6.0.100-preview.4.21255.9)
• AOT compile a Blazor WebAssembly app by publishing it
• Inspect the published output

Expected result:

• Only files that should be published with the app are present in the published wwwroot folder

Actual result:

• Published output contains C code, header files, and other implementation files like:
  • corebindings.c
  • driver.c
  • pinvoke.c
  • pinvoke.h
  • emcc-flags.txt
  • emcc-version.txt
  • etc.

This is most probably caused by the runtime. Will talk to them and update this issue accordingly.

@eerhardt do you have a tracking issue for this that we can dupe this against?

Seems to be a dupe of dotnet/runtime#48016 (mostly). I guess I wrote it as .c and .h files, but this also lists .txt files.
