🔴[`Attention`] Bert-based Models Attention Refactor (#38301) * clean start to bert refactor * some test fixes * style * fix last tests * be strict on positional embeddings, fixup according tests * cache support * more cache fixes, new causal API * simplify masks, fix tests for gen * flex attn, static cache support, round of fixes * ? * this time * style * fix flash attention tests, flex attention requires torch 2.7.x to work with multiple classes (as recompile strats force a size call which is wrongly interpreted before) * roberta * fixup sdpa remains * attention split, simplify args and kwargs, better typing * fix encoder decoder * fix test * modular roberta * albert * data2vectext, making it modular tomorrow * modular data2vec text * tmp disable * xmod + cache position fixes * whoops * electra + markuplm, small fixes * remove wrong copy * xlm_roberta + some embedding fixes * roberta prelayernorm * RemBert: remove copy, maybe doing it later * ernie * fix roberta offloading * camembert * copy fixes * bert generation + fixes on eager * xlm roberta xl * bridgetower (text) + seamlessv2 copy fixes * rocbert + small fixes * whoops * small round of fixups * NOTE: kernels didnt load with an earlier version, some fixup (needs another look bc cross deps) * the end of the tunnel? * fixup nllbmoe + style * we dont need this anymore * megatron bert is barely used, low prio skip for now * Modernize bert (template for others) NOTE: trying to push this through, might be overdue if not in time possible * check inputs for all others (if checkmarked) * fix bridgetower * style * fix encoder decoder (partially but cause found and fix also, just needs to be done for everything else) * proper fix for bert to force intermediate dict outputs * propagate to others * style * xlm roberta xl investigation, its the layernorm... * mobile bert * revert this, might cause issues with composed models * review * style
