Continues the work started in https://github.com/lightpanda-io/browser/pull/3070 Removes the _proto field from intermediary (non-leaf) elements and uses the relative positioning from the contiguous allocation. With the work done in previous commit, this is pretty mechanical. This essentially saves 8 bytes per type. Pretty small, but now Node->* is consistently designed 1 way. Empty leaf nodes are still an issue, and the _proto remains in them (for now). It's an issue because, if it's truly empty, the leaf can have the same address as the parent or a sibling. This is something we used to have problems with (hence some types have a _pad: bool). Solvable, but separately.
