Change `project`->`project_pin`.

Rationale: We will *certainly* want other kinds of projection. For example:

1. reference projection, for aliasing non-mut references. Exact mechanism under discussion, but there will need to be a projection operation, because normal Rust references cannot alias mut references.
2. (current goal) raw pointer projection: for example, the `ctor!()` macro projects into raw pointers. However, if we want to allow `ctor!()` to initialize things that cannot normally be initialized by value, it will need to ignore private padding fields during projection.

(I'll explain #2 more in the followup that actually implements it.)
