mining: store block create options in NodeContext

Browse Source 
Read configured mining options once during startup instead of parsing
options like -blockmaxweight each time a block template is generated.

Store the parsed startup options as BlockCreateOptions. Members left unset
keep representing unset options; hardcoded defaults are applied by
FlattenMiningOptions() before the options are used. IPC overrides and node
defaults can then be merged with the same option type used by
BlockAssembler.
