MDEV-13626: Import and adjust buffer pool resizing tests from MySQL 5.7

Browse Source 
Adapt from 10.2: git cherry-pick bfb5e1c3f0

buf_pool_t::chunk_t::create(), buf_pool_t::resize():
Restore or simplify the debug instrumentation.

buf_resize_callback(): Add DBUG_ENTER/DBUG_VOID_RETURN so that
the DBUG_EXECUTE_IF in buf_pool_t::resize() can be triggered.
