Split execute to smaller files.

[piobab]

Split execute to smaller rust files (make more consistent with newer Rover codebase and to be able to add unit test close to tested execute msg).

This PR only rearrange - no changes to original codebase. Refactor will come in smaller PR indepently.

I suggest we make an src/execute folder:

.
└── src/
    ├── execute/
    │   ├── asset.rs
    │   ├── borrow.rs
    │   ├── collateral.rs
    │   ├── config.rs
    │   ├── deposit.rs
    │   ├── instantiate.rs
    │   ├── mod.rs
    │   ├── repay.rs
    │   ├── uncollateralized_loan.rs
    │   └── withdraw.rs
    ├── contract.rs
    ├── lib.rs
    ├── query.rs
    └── state.rs

and in execute/mod.rs we do:

mod asset;
mod borrow;
mod collateral;
mod config;
mod deposit;
mod instantiate;
mod repay;
mod uncollateralized_loan;
mod withdraw;

pub use {
    asset::*, borrow::*, collateral::*, config::*, deposit::*,
    instantiate::*, repay::*, uncollateralized_loan::*, withdraw::*,
};

This way, in contract.rs we can still use execute::deposit, etc.

I believe this is also how it's organized in Rover repo.

nice! Rover has in the same directory. I think for now better to keep it similar so it doesn't influence others to different way of doing something (we can then rearrange everything in one go).
