🛠️ Rework benchmarks (#374)

## What?
- Fix and modify pallet-funding benchmarks post-simplification

## Why?
- Our benchmarks were overtly complicated, a result of the old logic.

## How?
- Fix syntax for new instantiator functions
- Simplify setup
- Delete old logic branches (e.g. no longer "unchanged" outcome for evaluator, no more benchmark for that)
- When 2 logic branches only had a small difference (e.g. 1 storage read/write), we now benchmark the worst case.

## Testing?
`cargo test --features runtime-benchmarks`
`just dry-run-benchmarks`
Keep in mind you need to do a cargo clean for it to work (dunno why)

## Anything Else?
Had to delete the runtime weights since the weight struct looks different. The runtime now uses the default `()` from the new weight file I generated in the pallet.

Soon we will generate the real pallet/runtime benchmarks in AWS
