Adds a `BoundMethod` SemIR node to represent an `x.F` bound method, with a new builtin type `BoundMethodType`. Reorganized conversion of call expression arguments to also check and convert a `self` parameter in the implicit parameters list. In passing, improved diagnostics and error recovery for bad call expressions. We now build a `call` node with the appropriate type and value category, but with invalid arguments, if the argument conversion failed, and diagnose calls to non-callable expressions. `addr self` methods don't work properly yet; the `addr` is ignored for now. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
