MDL-65809 upgrade: remove format_xxx_upgrade_remove_numsections

These functions were used only by deleted upgrade steps
so it's safe to proceed with straight deletion, considering
them internal. Deletion has been documented in corresponding
upgrade.txt files:

    - format_topics_upgrade_remove_numsections()
    - format_topics_upgrade_hide_extra_sections()
    - format_topics_upgrade_add_empty_sections()
    - format_weeks_upgrade_remove_numsections()
    - format_weeks_upgrade_hide_extra_sections()
    - format_weeks_upgrade_add_empty_sections()
