fix(l1): yield in-between blocks during batch execution (#3873)

**Motivation**

<!-- Why does this pull request exist? What are its goals? -->
Recently, while running full sync on sepolia network it has become a
common occurrence to suddenly lose all connected peers due to a `Broken
Pipe` error. Upon further investigation this seems to be due to block
execution being too intensive and leaving p2p unresponsive.
A quick fix for this was to add yields in-between block executions when
executing blocks in batches. This has solved the problem for sepolia
testnet (Over 1 Day without incidents).
This could also be improved by further integrating `spawned` into the
full sync process.
**Description**

<!-- A clear and concise general description of the changes this PR
introduces -->
* Add yields inbetween each block execution when executing blocks in
batches
<!-- Link to issues: Resolves #111, Resolves #222 -->

Closes #issue_number
