pallet-revive: Fix the contract size related benchmarks (#7568)

Partly addresses https://github.com/paritytech/polkadot-sdk/issues/6157

The benchmarks measuring the impact of contract sizes on calling or
instantiating a contract were bogus because they needed to be written in
assembly in order to tightly control the basic block size.

This fixes the benchmarks for:
- call_with_code_per_byte
- upload_code
- instantiate_with_code

And adds a new benchmark that accounts for the fact that the interpreter
will always compile whole basic blocks:
- basic_block_compilation

After this PR only the weight we assign to instructions need to be
addressed.
