MDEV-18249 ASSERT_COLUMN_MARKED_FOR_READ failed in ANALYZE TABLE

Browse Source 
The problem is the same as in MDEV-18166: columns in virtual field
expression are not marked for read, while the field itself does.

field->register_field_in_read_map() should be called for read-marking all
fields.

The test is reproduced only in 10.4+, however the fix is applicable to
10.2+.
