compiler: save both VM and smartcontract types

compiler: save both VM and smartcontract types
...
VM types are used in debugger, while smartcontract ones are used in
manifest. We can't save only one of them, because conversion in either
side is lossy:
1. VM has `Array` and `Struct` but smartcontract only has `Array`.
2. Smartcontract has `Hash160` etc, which are all `ByteString` or
`Buffer` in VM.
And to spice things a bit more, return type in debugger can be `Void`,
which corresponds to no real stackitem type (as it must exist).

manifest: add Safe
flag to method descriptor
...
`interop.Contex.AddMethod` sets `Safe` flag for native
contracts. This allows not to forget to change manifest
when changing call flags.
Also fixed invalid `Safe` flags for `Notary` and `Designate` contracts.
