Minimize the uniqueness of bytecodes

[xgreenx]

Duplicate of the FuelLabs/fuels-rs#1267, but for the TS SDK. It is better to have only one issue with the description since both SDKs have the same problems.

@xgreenx Contextually, we used to have a single multi-call .sw script that we used for everything. One of the problems was that it could handle a limited number of calls. Then, we replaced it with its dynamic counterpart using WASM fuel-asm and following how the Rust SDK was doing it.

Do you think we should return to having a statically compiled .sw script in this sense?

Or just change how we assemble it dynamically before calling it?

@arboleya I'd like to reassign this to library. IMO this will likely be handled by a script loader in a similar way to the new loader contract bytecode generation, that should live inside the script or program packages.

@arboleya Should we move this back to the backlog? It seems we still lack some information about how to proceed here
