MDEV-12353 preparation: Do not write MLOG_REC_MIN_MARK
btr_set_min_rec_mark(): Write MLOG_1BYTE instead of
MLOG_REC_MIN_MARK or MLOG_COMP_REC_MIN_MARK.
On ROW_FORMAT=COMPRESSED pages, the minimum record flag is not stored
at all. The flag is computed for the uncompressed page by
page_zip_decompress(). Hence, nothing needs to be logged for
ROW_FORMAT=COMPRESSED tables for this operation.
To facilitate crash-upgrade and hot backup from older versions,
we will retain the code to parse and apply the old log record types
MLOG_REC_MIN_MARK and MLOG_COMP_REC_MIN_MARK.
