Grouped batched attention + permute (#412) 

* grouped attn without batch validates; now move toward grouped batched attn

* grouped batched attention

* working

* remove debug logging

clean up

clean up

* reintroduce g_ prefix back to host tensor variables

* format

* rename file

* restore old file

* rename

* consolidate padded/non-padded attention example

* harmonize padding specialization in attn examples
