[experimental] Use account name directly for data types and codecs

[lorisleiva]

Assuming an AccountNode named Token, this PR makes the following changes to the generated client for the new web3.js:

// Before.
export type TokenAccountData = { ... }; // Data.
export type Token = Account<TokenAccountData>;
export type MaybeToken = MaybeAccount<TokenAccountData>;

// After.
export type Token = { ... }; // Data.
// Just use `Account<Token>` and `MaybeAccount<Token>` directly when needed.
