This preserves the constant values of the arguments to the thunk, which is important if the thunk requires conversion of an `IntLiteral` to some other type. This should become unnecessary once we have form support, but avoiding the indirection through a thunk function seems valuable even once that support is in place. To support this, track whether a function is a thunk on the Function object, and if so, what the callee of the thunk is. This information is also included in formatted SemIR when dumping the thunk.
