Windows builds broken when querying target-info from libSwiftScan

[artemcm]

After such queries result in target-infos containing double-quoted paths, e.g.:

    "sdkPath" : "'C:\\Library\\Developer\\Platforms\\Windows.platform\\Developer\\SDKs\\Windows.sdk'"

This failure is caused by #1335. For now we will disable libSwiftScan target info query on Windows while we understand how to get the paths right here.

The solution here will be to quote paths properly on Windows in the ArgsResolver:

Because simply using ' is not correct. We should probably piggy-back on @compnerd's work here:

Resolved with #1343
