Pull request overview
This PR implements caching mechanisms for reflection lookups to optimize serialization performance. The caching is applied to multiple areas including type enumerable item type resolution, converter lookups, serializable fields/properties detection, and field/property metadata lookups.
- Adds thread-safe caching using ConcurrentDictionary across multiple reflection-heavy operations
- Implements cache invalidation strategy for converter lookups when registry changes
- Provides new public APIs for cache management in TypeUtils

This pull request introduces significant performance improvements across the reflection-based serialization and type utilities in the codebase by adding thread-safe caching for various expensive reflection operations. These changes reduce redundant reflection calls, especially during population, serialization, and type analysis, which is crucial for large object graphs or frequent access patterns.
Reflection and Serialization Caching
BaseReflectionConverter<T>to avoid repeated reflection when populating objects from data; includes new methodsGetCachedField,GetCachedProperty, and a cache for serializable member names used in error reporting.BaseReflectionConverter<T>, ensuring that repeated serialization operations are much faster by reusing reflection results.

Reflector.Registryso that the best converter for a type is cached and reused; the cache is properly invalidated when converters are added or removed. [1] [2] [3] [4]Type Utilities Performance
TypeUtils, dramatically reducing the cost of determining element types for collections; includes a method to clear this cache when needed. [1] [2] [3]Error Reporting and Reflection Usage
