refactor(sdk-coin-atom): use abstract-cosmos

Ticket: WIN-1192

BREAKING CHANGE: restructured exports
- Removed constants overlapping with @bitgo/abstract-cosmos
- Removed common Interfaces exported by @bitgo/abstract-cosmos

Code dependent on the previously exported Interfaces/Constants needs to
be updated to import these from @bitgo/abstract-cosmos instead
