fix: support VersionedMessage in getFeeForMessage

[joncinque]

Problem

As noticed in https://solana.stackexchange.com/questions/4597/how-getfeeformessage-for-versioned-transaction, we can't use getFeeForMessage with a versioned message.

Summary of Changes

Similar to how versioned and legacy transactions are supported in sendTransaction, accept VersionedMessage in getFeeForMessage, and serialize it properly.

There's some mismatch in how the types are defined between VersionedTransaction and VersionedMessage, so here's the type definition for reference:

export type VersionedMessage = Message | MessageV0;
