Every version-gated setting was bookkept in four places that had to stay in sync by hand: the property boilerplate, SetLanguageVersion, GetMinimumRequiredVersion, and the [Category] display string - and that sync had already drifted in a handful of settings. A new source generator in ICSharpCode.Decompiler.Generators now derives all four from a single [DecompilerSetting] attribute on a partial property: backing field, accessors with change notification, the version-derived [Category], and both version methods. [Description] stays handwritten because its resource keys are irregular and are grepped from the resx. This commit is a 1:1 translation: the current inconsistencies are reproduced exactly (AffectsMinimumRequiredVersion = false on ExtensionMethods, UseLambdaSyntax and UseEnhancedUsing; no gate on SwitchOnReadOnlySpanChar), verified against the old build by comparing SetLanguageVersion and GetMinimumRequiredVersion behavior for every setting at every language version, plus a reflection diff of the full per-property attribute surface.
