Update tasks.json files for 64-bit VS Code

This change modifies the path used for PowerShell on Windows due to the
fact that 64-bit VS Code has been released (and is now being promoted as
the primary build).  We're only pointing to the System32 path for now
because VS Code doesn't provide a way to specify a different path in the
32-bit build.
