Rollup merge of #143730 - pascaldekloe:fmt-radix-trim, r=tgross35 ...

fmt of non-decimal radix untangled

Have the implementation match its decimal counterpart.

* Digit table instead of conversion functions
* Correct buffer size per radix
* Elimination of dead code for negative
* No trait abstraction for integers
