- backport of #36449 and #36756

Dougbu/check.solution.filters (#36449)

  * Check solution filters
  - confirm all mentioned projects are in AspNetCore.sln
  - clean up CodeCheck.ps1
    - avoid aliases
    - rework long lines
    - avoid deprecated `dotnet run -p`
    - improve output a bit
    - correct whitespace
  - there can be only one
    - we have just one solution file
    - solution file should mention projects _once_

  * Add missing projects to AspNetCore.sln
  - Middleware.slnf contained projects that no longer exist eg. NodeServices
    - VS also sorted the file and VS 2019 added ARM64 configurations
  - a few other solution filters still referenced removed and moved projects
  - correct capitalization in some solution filters

  Note: Unable to load some WiX projects in VS 2019 or _any_ in VS 2022 (WiX extension unavailable for 2022)

  * Remove trailing comma in a solution filter

Put concatenated `string`s in parentheses (#36756)

  - follow-up to 779db7f3
  - errors occur but point to the `+` sign instead of displaying real problem
