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
#### Original Performance
```
fmt::write_10ints_bin 393.03ns/iter +/- 1.41
fmt::write_10ints_hex 316.84ns/iter +/- 1.49
fmt::write_10ints_oct 327.16ns/iter +/- 0.46
```
#### Patched Performance
```
