Remove initialize_resource<T> and friends (#12307)

Browse source 
# Objective
`initialize_resource<T>` and it's non-send equivalent is only used in
two locations each. Fix #6285.

## Solution
Remove them, replace their calls with their internals. Cut down on a bit
of generic codegen.

This does mean that `initialize_resource_internal` is now `pub(crate)`,
but that's likely OK given that only one variant will remain once
NonSend resources are removed from the World.
