MINOR: stats: provide ctx for dumping functions

This is a minor refactor to allow stats_dump_info_* and stats_dump_fields_*
functions to directly access stat ctx pointer instead of explicitly
passing stat ctx struct members to them.

This will allow dumping functions to benefit from upcoming ctx updates.
