[Windows] Writing Data to "CON" path creates "CON" file in CWD instead of printing to stdout

[jmschonfeld]

Describe the bug
Writing Data to the path/URL "CON" results in a "CON" file being created in the CWD instead of printing that data to stdout

To Reproduce
Given the following unit test in swift-foundation

    #if os(Linux) || os(Windows)
    @Test
    #else
    @Test(.disabled("This test is not applicable on this platform"))
    #endif
    func writeToSpecialFile() throws {
        #if os(Windows)
        let path = URL(filePath: "CON", directoryHint: .notDirectory)
        #else
        let path = URL(filePath: "/dev/stdout", directoryHint: .notDirectory)
        #endif
        #expect(throws: Never.self) {
            try Data("Output to STDOUT\n".utf8).write(to: path)
        }
    }

it creates the file "CON" in the CWD instead of printing "Output to STDOUT" to stdout

Expected behavior
As was the case in previous releases IIRC, I expect this to output to STDOUT and not write to the CWD

Configuration (please complete the following information):

• Swift Version: main branch of swift-foundation with the June 22nd Windows main snapshot toolchain
• OS: Windows
• OS Version: Windows 10
