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:

swift-driver/Sources/SwiftDriver/Execution/ArgsResolver.swift

Line 119 in 3f15981

return quotePaths ? "'\(actualPath)'" : actualPath

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

swift-driver/Sources/SwiftDriver/Utilities/System.swift

Line 58 in 4f3d37f

func quote(_ argument: String) -> String {

Resolved with #1343
