Refactor the last references to `rb_shape_t`

The type isn't opaque because Ruby isn't often compiled with LTO,
so for optimization purpose it's better to allow as much inlining
as possible.

However ideally only `shape.c` and `shape.h` should deal with
the actual struct, and everything else should just deal with opaque
`shape_id_t`.
