055cccde - chore(langchain): allow injection of `ToolRuntime` and generic `ToolRuntime[ContextT, StateT]` (#33546)

chore(langchain): allow injection of `ToolRuntime` and generic `ToolRuntime[ContextT, StateT]` (#33546) Adds special private helper to allow direct injection of `ToolRuntime` in tools, plus adding guards for generic annotations w/ `get_origin`. Went w/ the private helper so that we didn't change behavior for other injected types.
