seq: Move extendedbigdecimal.rs to uucore/features/format

Will make it possible to directly print ExtendedBigDecimal in `seq`,
and gradually get rid of limited f64 precision in other tools
(e.g. `printf`).

Changes are mostly mechanical, we reexport ExtendedBigDecimal directly
in format to keep the imports slightly shorter.
