CB-7820 Make cordova platfrom restore not stop if a platforms fails to restore

handles restoration for each platform separately so that if one fails installation for
others continues. Also makes a change on how the host is checked to allow such errors
not to completely halt the execution.

CB-7311 Fix xcode project manipulation on Windows host

When adding plugins on Windows, plugman will insert incorrect paths,
which also contain backslashes into the xcode project files. This breaks
builds of the iOS app in Xcode and requires manual editing of the
project file.

On all non-Windows platforms, where the path separator is already `/`,
the performed replace should be a noop, on Windows it fixes the paths in
the project file.
