feat: add Secp256k1 support to solana-web3.js (#12958)
* feat: add secp256k1 instruction * feat: use buffer-layout for encoding as well * style: use consistent naming for types * style: update typings and make program functions static * fix: attempt to resolve rollup issue * fix: expose sysvar in typings * fix: remove decode instruction functionality (for now)
