bors 829d69b9c6 Auto merge of #74827 - ssomers:btree_cleanup_insert, r=Mark-Simulacrum
Move bulk of BTreeMap::insert method down to new method on handle

Adjust the boundary between the map and node layers for insertion: do more in the node layer, keep root manipulation and pointer dereferencing separate. No change in undefined behaviour or performance.
