--override option does not correctly treat variables with spaces (like $Env:ProgramFiles)

Brief description of your issue

While trying to override INSTALLDIR directory for Java JRE I've used the following command line:

winget.exe install --id Oracle.JavaRuntimeEnvironment --override "/s INSTALLCFG=`"$Env:TEMP\JavaRE64.cfg`" INSTALLDIR=`"$Env:ProgramFiles\Java\jre8`""

Argument parsing does not handle correctly $Env:ProgramFiles:

override arguments end at C:\Program and Files\Java\jre8 is treated as a Winget parameter instead of part of override.

So winget tries to install an application called Files\Java\jre8 that, obviously, does not exist ;-)

Steps to reproduce

Execute the following command:

winget.exe install --id Oracle.JavaRuntimeEnvironment --override "/s INSTALLDIR=`"$Env:ProgramFiles\Java\jre8`""

Expected behavior

Oracle JRE installed at C:\Program Files\Java\jre8.

Actual behavior

Winget complaints about inexistent Files\Java\jre8 application: No package found matching input criteria.

The issue names no implementation files or tests. Reproduce the PowerShell command and inspect the CLI argument parsing for --override; done means the full path containing spaces remains part of the override value and is not treated as a separate package argument.
