Account for items weight in pallet parameters

[gonzamontiel]

This PR addresses potential discrepancies in weight measurement by accounting for all parameters at block initialization.

It introduces a mechanism to account for the weight (both ref_time and proof_size) of all parameters at the start of each block. This is necessary to account for parameters that might be accessed in scenarios not covered by benchmarking. An example could be the parameter usage within the OnChargeTransaction of the pallet_transaction_payment.
