instruction: Derive everything for wasm build (#3606)

#### Problem

As noticed in
solana-labs/solana-program-library#7489, the
wasm build for `Instruction` doesn't contain `Clone`. This is because we
missed the derivations for the wasm version of `Instruction` in
#1658.

#### Summary of changes

Looking back through that PR, I noticed that we only missed those
additional derives on `Instruction`, so just fix those in `Instruction`.

Since this is fixing a small regression for wasm builds, I think we
should backport the change to v2.1.
