[Metal] Fix indirect dispatch retaining stack garbage as a resource (#24641)

iree_hal_metal_command_buffer_prepare_dispatch built a resources[2]
array for direct/indirect dispatch but passed &executable (the address
of the parameter) to iree_hal_resource_set_insert instead of the
resources array. For indirect dispatch (resource_count==2) this read the
stack word adjacent to the parameter and retained it as a resource,
corrupting the resource set and crashing on command-buffer teardown
(release dereferenced a NULL vtable).

Pass resources so both the executable and the indirect workgroup-count
buffer are retained correctly. Fixes the DispatchIndirectParameters and
QueueDispatchIndirectParameters CTS segfaults (ctest #1307, #1309).
