core: miner: reduce allocations in block building (#33375)
I recently went on a longer flight and started profiling the geth block
production pipeline.
This PR contains a bunch of individual fixes split into separate
commits.
I can drop some if necessary.


Benchmarking is not super easy, the benchmark I wrote is a bit
non-deterministic.
I will try to write a better benchmark later
