Use reflection for DexFile and XResources

Avoid direct references to dalvik.system.DexFile and android.content.res.XResources by using reflection and guarded calls. LSPApplication now constructs and injects the provider dex via reflective DexFile/DexPathList$Element creation inside a try/catch to handle deprecation/compat issues on newer Android versions and log failures. LSPLoader replaces the direct XResources.setPackageNameForResDir call with a reflective invocation (with warning logs) to prevent class resolution failures under strict boot classloader namespace delegation. Also added logging and minor import/constant adjustments to improve robustness and diagnostics.
