Fix undefined behavior in shape.c
Under strict aliasing, writing to the memory location of a different
type is not allowed and will result in undefined behavior. This was
happening in shape.c due to `rb_id_table_lookup` writing to the memory
location of `VALUE *` that was casted from a `rb_shape_t **`.
This was causing test failures when compiled with LTO.
Fixes [Bug #19248]
