[VLMs] support attention backends (#37576)

Browse Source 
* update models

* why rename

* return attn weights when sdpa

* fixes

* fix attn implementation composite

* fix moshi

* add message

* add typings

* use explicitly all flags for each attn type

* fix some tests

* import what is needed

* kosmos on main has ew attention already, yay

* new models in main, run fixup

* won't fix kosmos yet

* fix-copies

* clean up after rebasing

* fix tests

* style

* dont cast attns to fp32

* did we update ruff? oke, let's just do what it asks

* fix pixtral after rebase
