Add slice_cond and per-model context window cond resizing (#12645)

Browse Source 
* Add slice_cond and per-model context window cond resizing

* Fix cond_value.size() call in context window cond resizing

* Expose additional advanced inputs for ContextWindowsManualNode

Necessary for WanAnimate context windows workflow, which needs cond_retain_index_list = 0 to work properly with its reference input.
