Retarget .NET Framework 4.5.2 to 4.6

Recipe IDOpenRewrite.Recipes.CSharp.Migration.Dotnet.NetFramework.UpgradeToNetFramework46

ArtifactOpenRewrite.Recipes.CSharp.Migration.Dotnet

Retargets a .NET Framework 4.5.2 project to 4.6. Updates <TargetFrameworkVersion> to v4.6, <TargetFramework> to net46, the app.config <supportedRuntime sku>, and the web.config targetFramework. Includes all earlier steps (4.0 -> 4.5.2). 4.6 is where <AppContextSwitchOverrides> is introduced. Notable retargeting changes: TLS now restricts to 1.0/1.1/1.2 and drops SSL3/RC4 (opt out via Switch.System.Net.DontEnableSchUseStrongCrypto=true); certificate EKU validation is added; CurrentCulture/CurrentUICulture flow across async tasks (Switch.System.Globalization.NoAsyncCurrentCulture=true); the 64-bit RyuJIT replaces the legacy JIT (<useLegacyJit enabled="1"/> to revert); XmlWriter throws on invalid surrogate pairs. The accompanying Find recipe flags ServicePointManager/TLS code for review. See https://learn.microsoft.com/en-us/dotnet/framework/migration-guide/retargeting/4.6.x.
