Refactor exception handling with new mapping system

Browse Source 
Updated `GlobalExceptionHandlerOptions` to use a new `_registeredMappings` dictionary for `HttpExceptionMapping` objects, enhancing flexibility in mapping exceptions to HTTP responses. Renamed `RegisterException` to `Add` to reflect its new functionality. Removed the `HttpResponse` record definition and introduced a new `HttpExceptionMapping` record, which includes a static `Create` method for easier instantiation of mappings.
