Incremental compilation: getNewFiles does not pick up newly generated files on Windows

[dioxic]

Using KSP 1.6.10-1.0.4

Newly generated sources are not picked up by resolver.getNewFiles() and, consequently, resolver.getSymbolsWithAnnotation().

This is identical to #820 but on Windows.

class MyProcessor(
    private val environment: SymbolProcessorEnvironment
) : SymbolProcessor {
    var i = 0
   
    override fun process(resolver: Resolver): List<KSAnnotated> {
        println("[$i] Handling NEW: ${resolver.getNewFiles().joinToString { it.toString() }}")
        println("[$i] Handling ALL: ${resolver.getAllFiles().joinToString { it.toString() }}")
        i++

        resolver.getNewFiles()
            .forEachIndexed { idx, file ->  
                // logic approximately boils down to
                // if i == 0 generate new file with name `NewFile_idx.kt` 
            }
            
        return emptyList()
    }
}

Output on Linux (RHEL derivative):

[0] Handling NEW: File: MyFile.kt
[0] Handling ALL: File: MyFile.kt
[1] Handling NEW: File: NewFile_0.kt
[1] Handling ALL: File: MyFile.kt, File: NewFile_0.kt
[2] Handling NEW: 
[2] Handling ALL: File: MyFile.kt, File: NewFile_0.kt

Output on Windows (Windows 10 Pro):

[0] Handling NEW: File: MyFile.kt
[0] Handling ALL: File: MyFile.kt
[1] Handling NEW: File: 
[1] Handling ALL: File: MyFile.kt, File: NewFile_0.kt
