gh-87790: support thousands separators for formatting fractional part of floats (#125304)
```pycon
>>> f"{123_456.123_456:_._f}" # Whole and fractional
'123_456.123_456'
>>> f"{123_456.123_456:_f}" # Integer component only
'123_456.123456'
>>> f"{123_456.123_456:._f}" # Fractional component only
'123456.123_456'
>>> f"{123_456.123_456:.4_f}" # with precision
'123456.1_235'
```
