Richard Smith 842b471e67 Perform in-place initialization for tuples and structs (#3246) ...

This implements initializing expression semantics for structs and
tuples, following #2006 and discussions since.

Tuple and (and analogously, struct) literals are treated as having a
mixed expression category that is later resolved based on how the
literal is used, as either a tuple initializer or a tuple value, at
which point we create a `TupleInit` or `TupleValue` that represents the
formation of the tuple initializer or tuple value from the tuple
literal.

There's quite a lot of TODOs here, and the SemIR representation is still
not quite right, but this seems like a good place to checkpoint some
incremental progress.
