[Inspection] debug_dumpBlock

Retrieves the state that corresponds to the block number and returns a list of accounts (including storage and code).

NOTE: This function correctly returns the state for a few latest, currently 4, block numbers. Retrieving older block state is restricted depending on the value set for the command-line option --state.block-interval (default: 128). This means that the function performs the state retrieval against only the block numbers that are multiples of state.block-interval. For example, when state.block-interval is 128, this function returns the state for the block numbers "0x0", "0x80", "0x100", "0x180", and so on. If the block number is not a multiple of state.block-interval, it returns 'missing trie node' error.
