Subject: [PATCH] AK: Give IntrusiveBinaryHeap template args named types

Works around https://gcc.gnu.org/PR70413. Without this, the next
commit would cause -Wsubobject-linkage warnings for AK/BinaryHeap.h
when used in LibCompress/Huffman.h.

We can undo this once we're on GCC 14 everywhere.

No behavior change.
