v2.1: Extract solana-nonce crate (backport of #3082)

[mergify]

Problem

solana_program::nonce imposes a solana_program dependency on solana_svm

Summary of Changes

• Move to its own crate and re-export for backwards compatibility
• Make serde optional in the new crate

This branches off #2969 so that needs to be merged first
