[roll] Roll fuchsia [starnix][binder] Optimize HandleTable with O(1) reverse lookup

Replace the linear Slab iteration in HandleTable::find_ref_for_object
with an indexed BTreeMap<ArcKey<BinderObject>, usize> reverse lookup
map. This eliminates O(n) handle scanning during object translation in
binder transactions, cutting median flow latency by 16.2% and reducing
HandleThreadWrite CPU time by 6.3%.

Test: Verified via cold app launch benchmarks and trace flows.
