Extract data structures and pure functions into shareable crate

[jeff-sqds]

This PR is an attempt to reduce the overall vulnerability of consumers of the smart-account-program rust components by enabling data structures and their pure functions to be canonically defined alongside the solana programs they're chiefly intended for, while removing the need for consumers of those types and functions from importing the entire solana program and anchor dependency chain. This is an attempt to mitigate the brittle duplication of copy-pasting types and methods previously seen from consumers of the V4 program as well as maintain a single canonical source of the types by the originating project so consumers are not required to vet potentially malicious copies in the crates registry when constructing consuming applications.

Functionally this change migrates type definitions and function implementations into a squads_smart_account_program_types crate that includes optional implementations of borsh and anchor dependencies for "batteries included but not installed" deriving of common traits. These are then imported and enabled by default in the program crate. The types crate is structured to mirror the module layout of the program crate for familiarity and usage internal to the program crate is maintained via re-exports.
