transfer-hook-interface: Remove solana-program dependency (#7442)

* transfer-hook-interface: Remove solana-program dependency

#### Problem

The transfer-hook-interface pulls in solana-program, but it doesn't need
to.

#### Summary of changes

Use the component crates. The only breaking change is the re-exports. It
still uses a dev-dependency on solana-program since the system program
id isn't available yet outside of solana-program.

* Add missing solana-pubkey feature

* Add all test programs

* Run cargo fmt

* Fixup imports
