Centralize errors making them to typed errors, get rid of "NamedError"

[izri16]

Currently, errors are given "types" by setting their name with a string identifier, which is not centrally controlled and makes checking its specific type unwieldy. Possibly a good source of inspiration could be how errors are defined in ledgerjs library recently refactored by Ppershing: https://github.com/vacuumlabs/ledgerjs-cardano-shelley/blob/develop/src/errors/deviceStatusError.ts

TODO:

• refactor unify the way we set errors to state
• refactor setError, captureBySentry
• refactor errorsWithHelps into enum
• refactor getErrorMessage interface so it receives custom error classes
