MDEV-12353: Optimize page_cur_delete_rec() logging
page_mem_free(): When deleting the last record of a page,
do not add it to the PAGE_FREE list, but instead truncate the
PAGE_HEAP_TOP. Modify the page header fields by writing fewer
records.
page_cur_delete_rec(): Let page_mem_free() reset the PAGE_LAST_INSERT.
page_header_reset_last_insert(): Issue memset(), not memcpy(), for
the ROW_FORMAT=COMPRESSED page.
