[clang] Skip re-building lambda expressions in parameters to consteval fns.

[clang] Skip re-building lambda expressions in parameters to consteval fns.

As discussed in this [comment](https://github.com/llvm/llvm-project/issues/56183#issuecomment-1224331699),
we end up building the lambda twice: once while parsing the function calls and then again while handling the immediate invocation.

This happens specially during removing nested immediate invocation.
Eg: When we have another consteval function as the parameter along with this lambda expression. Eg: `foo(bar([]{}))`, `foo(bar(), []{})`

While removing such nested immediate invocations, we should not rebuild this lambda. (IIUC, rebuilding a lambda would always generate a new type which will never match the original type from parsing)
