Subject: [PATCH] Various Powershell Fixes (#7854)

* Remove incorrect x64 error message when showing usage description

* Add missing escape characters in usage description

The actual environment variable value would be printed without these
escape characters.

* Add missing quotation marks in usage description

* Also test existence of sha and signature files

For multiple reason the executable could be downloaded, but not the
signature files. Later on the script will error out because these files
are lacking.
