fix: resolve ClangTidy Android CI failure caused by DebugView.h warnings

[Copilot]

PatriceJiang/clang-tidy-action was crashing with Offset out of range! because clang-tidy generated fix entries in clang-fixes.yaml with byte offsets beyond the file boundaries — triggered by two warnings in DebugView.h.

Changes

• native/cocos/renderer/pipeline/DebugView.h
  • Remove else/else if after return in getType() (readability-else-after-return)
  • Remove duplicate private: access specifier (readability-redundant-access-specifiers)

// Before
if (_singleMode != DebugViewSingleType::NONE) {
    return RenderingDebugViewType::SINGLE;
} else if (!_lightingWithAlbedo || _csmLayerColoration) {   // ← else-after-return
    return RenderingDebugViewType::COMPOSITE_AND_MISC;
} else { ... }

// After
if (_singleMode != DebugViewSingleType::NONE) {
    return RenderingDebugViewType::SINGLE;
}
if (!_lightingWithAlbedo || _csmLayerColoration) {
    return RenderingDebugViewType::COMPOSITE_AND_MISC;
}

The redundant second private: block was merged into the existing one by removing the duplicate specifier.
