MDEV-35000 preparation: Clean up dict_table_t::stat

Browse Source 
innodb_stats_transient_sample_pages, innodb_stats_persistent_sample_pages:
Change the type to UNSIGNED, because the number of pages in a table
is limited to 32 bits by the InnoDB file format.

btr_get_size_and_reserved(), fseg_get_n_frag_pages(),
fseg_n_reserved_pages_low(), fseg_n_reserved_pages(): Return uint32_t.
The file format limits page numbers to 32 bits.

dict_table_t::stat: An Atomic_relaxed<uint32_t> that combines a
number of metadata fields.

innodb_copy_stat_flags(): Copy the statistics flags from
TABLE_SHARE or HA_CREATE_INFO.

dict_table_t::stats_initialized(), dict_table_t::stats_is_persistent():
Accessors to dict_table_t::stat.
