MDEV-12353: Replace MLOG_*_END_COPY_CREATED

Instead of writing the high-level redo log records
MLOG_LIST_END_COPY_CREATED, MLOG_COMP_LIST_END_COPY_CREATED
write log for each individual insert of a record.

page_copy_rec_list_end_to_created_page(): Remove.

This will improve the fill factor of some pages.
Adjust some tests accordingly.

PageBulk::init(), PageBulk::finish(): Avoid setting bogus limits
to PAGE_HEAP_TOP and PAGE_N_DIR_SLOTS. Avoid accessor functions
that would enforce these limits before the correct ones are set
at the end of PageBulk::finish().
