MDEV-18452 ASAN unknown-crash in Field::set_default upon SET bit_column = DEFAULT
Field_bit for BIT(20) uses 2 full bytes in the record,
with additional 4 uneven bits in the "null bit area".
Field::set_default() called from Field_bit::set_default() erroneously
copied 3 bytes instead of 2 bytes from the record with default values.
Changing Field::set_default() to copy pack_length_in_rec() bytes
instead of pack_length() bytes.
