Fix source-gen resolvers dropping custom parameter expression builders

Pull request overview

Adds coverage and runtime support so source-generated resolvers honor AddParameterExpressionBuilder(...) injections (instead of turning those parameters into GraphQL field arguments), while keeping the “no custom builder registered” behavior intact.

Changes:

• Introduces a new integration-test mutation (createExport) and a CurrentUser CLR type to validate custom parameter injection vs. implicit argument inference.
• Adds integration tests that assert the parameter is not exposed as a GraphQL argument and that the injected value is actually used at execution time.
• Updates CustomParameterExpressionBuilder<TArg> to participate in the source-gen parameter binding pipeline (IParameterBindingFactory / IParameterBinding).

src/HotChocolate/Core/test/Types.Analyzers.Integration.Tests/snapshots/IntegrationTests.Schema_Snapshot.snap	Updates schema snapshot to include createExport and inferred CurrentUserInput when no custom builder is registered.
src/HotChocolate/Core/test/Types.Analyzers.Integration.Tests/snapshots/IntegrationTests.Schema_Snapshot_Without_ConnectionName_Inference.snap	Same schema snapshot update for the “no connection name inference” configuration.
src/HotChocolate/Core/src/Types/Internal/CustomParameterExpressionBuilder.cs	Implements binding factory/binding so source-gen can resolve parameters via custom expression builders.
