Sync block body

[pinges]

PR description

This PR changes the SNAP and CHECKPOINT sync to reduce the memory requirements by not decoding the block bodies requested from peers. This results in less memory and CPU usage during the sync. This PR does make sure that the properties of the syncs are the same as before, e.g. transaction indexing and block added events haven't changed.

Note: this PR does not significantly reduce the sync time on it's own, because the bottleneck is the import step of the download pipeline. It will however allow us to increase the parallelism of the pipeline because of the reduced memory and CPU usage. Once the import step is improved that increase in parallelism will allow us to reduce the sync time.

Note: Not decoding receipts during the sync does improve the memory and CPU usage as well. This has been shown in a POC.
