Richard Smith e69c3fd978 Support list initialization of C++ classes that is performed via a constructor call. (#6660) ...

The general strategy here is to import the constructor with a signature
that directly matches the argument. The intent is that the imported
function will eventually be usable directly as the `ImplicitAs.Convert`
function in a generated `impl`.

For initialization from a tuple, for example `(1, 2)`, we import the
selected constructor with a signature that takes a tuple pattern:

  `fn Class.Class((a: i32, b: i32)) -> Class;`

In order to support that, this PR also adds support in general for tuple
patterns in function signatures. It turns out the implementation was
already very close to allowing this.
