Build native assets by default (#22611)

* Build native assets by default
  - #22556
  - make `-BuildNative` primarily useful when you want _only_ native assets
    - can also build `-Projects` with desktop `msbuild` using `-BuildNative`
  - remove `-ForceCoreMsbuild` option
  nit: extra `Remove-Item`s caused `MSBuild` function to do redundant work

* !fixup! Get `/bl` options working again
  nit: Place SiteExtensions .binlogs correctly wherever script is run from
* !fixup! Remove *.vcxproj from Servers build
  - native projects are built implicitly
* !fixup! Remove `-buildNative` from IIS build script
