Fix tflongformer int dtype (#18907)

Browse Source 
* Use int64 throughout TFLongFormer

* make style

* Do some more fixed casting in TFLongFormer

* Fix some wonky "is None" conditionals

* Cast all the dtypes, salt the earth

* Fix copies to TFLED as well and do some casting there

* dtype fix in TFLongformer test

* Make fixup

* Expand tolerances on the LED tests too (I think this is a TF32 thing)

* Expand test tolerances for LED a tiny bit (probably a Tensorfloat thing again)
