fix(rpc sync_state): fix ckb-cli rpc sync_state error

[chanhsu001]

when ckb-cli rpc sync_state, the error message is: missing field "unknown_header_list_size"

Cause

sync_state() in client.rs wrongly returns PeerSyncState instead of SyncState

Fix

• fix sync_state() in client.rs, return SyncState
• add corresponding SyncState in types.rs

Verify

For the inner rpc client it has been fixed in ckb-sdk v1.0.1, for the wrapper type (types::SyncState) please rebase the PR.
