Changes:
marshallpierce/rust-base64@v0.13.1...v0.21.0
`base64::{encode,decode}` are now deprecated in favor of an API that
explicitly selects an `Engine`. Migrated all calls to the new API.
* reorganize error using DRY principle
* rename error `Format` to `Deserialization`
* Rename `EncryptionError` to `DiscreteLogError`
* resolve errors from rebase
* resolve clippy
* change `ProofInstructionError` to `ProofError`
Move all syscall declarations under solana_program::syscalls. If the target
supports static syscalls (sbfv2), then actually define them statically to avoid
dynamic relocations.
