Problem

solana_program::vote imposes a solana_program dep in a few places

Summary of Changes

• Move to its own crate and re-export for backwards compatibility
• Make serde and bincode optional in the new crate
• Remove thiserror and replace with inline impl

[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.
