<i18n dev> RFR: 8262744: Formatter '%g' conversion uses wrong format for BigDecimal rounding up to limits [v2]

[Ian Graves]

> This fixes a bug where the formatting code for `%g` flags incorrectly tries to round `BigDecimal` after determining whether it should be a decimal numeric format or a scientific numeric format. The solution rounds before determining the correct format.
