Convert cql-to-elm to Kotlin Multiplatform (Kotlin feature branch)

[antvaset]

What's included:

• The cql-to-elm module is converted to Kotlin Multiplatform.
• Kotlin version bumped to 2.0 (kotlin.uuid.Uuid only available since Kotlin 2.0).
• Shim implementations for Stack, isLeapYear, isDigit, isLetter, isLetterOrDigit.
• java.util.regex.Pattern replaced with kotlin.text.Regex.
• CqlCompiler, CqlTranslator, LibraryManager, ModelManager, LibrarySourceLoader are split into Common* and JVM-specific subclasses and subinterfaces.
• A simple @JsExport-friendly CQL-to-ELM helper (can be used to compile CQL to ELM in JS):

cqlToElm(
    cqlText: String,
    getModelXml: (
        id: String,
        system: String?,
        version: String?
    ) -> String,
    getLibraryCql: (
        id: String,
        system: String?,
        version: String?
    ) -> String? = { _, _, _ -> null },
    validateUnit: (unit: String) -> String? = { null },
    outputContentType: String = LibraryContentType.JSON.mimeType()
): String
