MDEV-25202: JSON_TABLE: Early table reference leads to unexpected result set

Browse Source 
Address review input: switch Name_resolution_context::ignored_tables from
table_map to a list of TABLE_LIST objects. The rationale is that table
bits may be changed due to query rewrites, etc, which may potentially
require updating ignored_tables.
