[ledger_client] Add fit::promise<> wrappers for some common Ledger API calls.

These wrappers turn various Page and PageSnapshot calls into
fit::promise<> equivalents. Where a ledger.Status is returned, an OK
status is translated into an ok() result, and any other value is
translated into an error() result.

TEST=future CLs exercise these methods
