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

[GabrielePicco]

Description

Currently, we cannot use extra acconts in combinations with normal accounts 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
