Auto merge of #50352 - porglezomp:btree-no-empty-alloc, r=Gankro
Don't allocate when creating an empty BTree Following the discussion in #50266, this adds a static instance of `LeafNode` that empty BTrees point to, and then replaces it on `insert`, `append`, and `entry`. This avoids allocating for empty maps. Fixes #50266 r? @Gankro
