Aske Simon Christensen 0549295eb4 [vm/aot] Partition table selector IDs based on hierarchy connectedness.

Compared to assigning selector IDs purely by name, this improves the
packing of selector rows, reducing the in-memory size of the dispatch
table by typically around 20% (75k memory usage reduction for Flutter
Gallery on ARM64).

It also improved tree shaking of methods called (or rather, not called)
via dispatch table calls, reducing the total snapshot sizes of Flutter
benchmarks by up to 2.1% (Flutter Gallery: ARM 1.8%, ARM64 2.1%).
