Nayuta Yanagisawa 2ecd39c983 MDEV-27240 SIGSEGV in ha_spider::store_lock on LOCK TABLE 
The commit e954d9de gave different lifetime to wide_share and
partition_handler_share. This introduced the possibility that
partition_handler_share could be accessed even after it was freed.

We stop sharing partitoiin_handler_share and make it belong to
a single wide_handler to fix the problem.
