feat(solana): add solana-ibc-sdk, decouple relayer and solana-ibc-types and remove duplicated types

[mariuszzak]

Description

• Introduce solana-ibc-sdk — an auto-generated off-chain SDK that produces typed instruction builders, PDA
  derivation helpers, account structs and event types from Anchor IDL files for all six Solana programs
  (ics26-router, ics07-tendermint, attestation, ift, ics27-gmp, access-manager)

• Extract solana-ibc-borsh-header and solana-ibc-gmp-types into standalone crates (previously modules inside
  solana-ibc-types)

• Decouple the relayer and operator from solana-ibc-types: they now depend on solana-ibc-sdk and the new
  leaf crates instead. solana-ibc-types is now only shared between on-chain Solana programs.

• Remove hand-maintained type duplicates, serialization compatibility tests and the light-client feature from
  solana-ibc-types (moved to solana-ibc-borsh-header)

• Add a dependency graph to the Solana README
