Avoid doing multiple validations on transactionsRoot and receiptsRoot during syncing

[jframe]

Description

The idea is to avoid calculating the transactionsRoot and receiptsRoot twice during syncing. The transactionsRoot along with the ommersHash, withdrawalsRoot and requestsRoot is calculated in the GetBodiesFromPeerTask to verify the blocks that have been downloaded and again in MainnetBlockBodyValidator when the block is imported. Similar story for receipts with it being calculated once in the download to verify and again in the MainnetBlockBodyValidator.

A previous PR was made to improve this #5679 but the suggested approach is to use a cache instead.

Acceptance Criteria

• Removes duplicate calculation of roots
• Improves syncing time
