Introduces the `BindingPattern` and `SymbolicBindingPattern` insts, and a separate stack of pattern blocks that they are emitted into. The intent is to generate the corresponding pattern-matching insts (like `BindName`) from them in a separate pass, but that is deferred to future PRs. See [here](https://docs.google.com/document/d/1U_vQH17V893J9aF1LJXUnFYBNSs2MjKl4bJPaWCB2zo/edit?usp=sharing&resourcekey=0-w0xGYZ0An31Kpz-wvzSXwQ) for the design this is based on, but note that during review we have chosen to deviate from that design by putting the patterns in separate blocks, and omitting the "forward references" from a `BindingPattern` to its corresponding `BindName`. This in turn necessitates having separate inst kinds for symbolic and non-symbolic binding patterns. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
