Extract account-info crate

[kevinheavey]

Problem

account_info.rs needs to be made available outside solana-program

This branches off #2413 so that needs to be merged first

Summary of Changes

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

[mergify]

The Firedancer team maintains a line-for-line reimplementation of the
native programs, and until native programs are moved to BPF, those
implementations must exactly match their Agave counterparts.
If this PR represents a change to a native program implementation (not
tests), please include a reviewer from the Firedancer team. And please
keep refactors to a minimum.
