[Bug] Lifetime difference in the `extra accounts` and `normal account`

## Description

Currently, we cannot use [extra acconts](https://github.com/magicblock-labs/bolt/blob/main/examples/system-apply-velocity/src/lib.rs#L35) in combinations with [normal accounts](https://github.com/magicblock-labs/bolt/blob/main/examples/system-apply-velocity/src/lib.rs#L18) to create for example a CpiContext to perform a CPI due to lifetime conflicts.

## Notes

Modify how `extra accounts` macro inject the helpers and set proper lifetimes: https://github.com/magicblock-labs/bolt/blob/main/crates/bolt-lang/attribute/extra-accounts/src/lib.rs#L80

Start with crates/bolt-lang/attribute/extra-accounts/src/lib.rs around the macro helper injection, then compare the extra and normal account examples in examples/system-apply-velocity/src/lib.rs. Reproduce the lifetime conflict while building a CpiContext with both account types; done means the combination compiles without lifetime conflicts.
