Reduce cognitive complexity in 6 methods flagged by analyzers

[AGiorgetti]

Description

The build reports 6 Cognitive Complexity violations from analyzers:

Method	Complexity	Allowed	File
PatchForResolutionContextTracking	20	15	DetectIncorrectUsageOfTransientDisposables.cs
PatchForDetectIncorrectUsageOfTransientDisposables	27	15	DetectIncorrectUsageOfTransientDisposables.cs
CreatePatchedDescriptor	16	15	DetectIncorrectUsageOfTransientDisposables.cs
DependsOnResolutionFunc	16	15	ServiceCollectionExtensions.KeyedService.cs
KeyedDependsOnResolutionFunc	16	15	ServiceCollectionExtensions.KeyedService.cs
CreateServiceProvider	18	15	ServiceProviderFactory.cs

Suggested Approach

• Extract keyed vs non-keyed handling into separate helper methods in patching code
• Extract common parameter resolution logic from DependsOnResolutionFunc/KeyedDependsOnResolutionFunc
• Extract open-generic logging into a helper in CreateServiceProvider
