Bug#31384 DATE_ADD() and DATE_SUB() return binary data
Problem: DATE_ADD() is a hybrid function and can return
DATE, DATETIME or VARCHAR data type depending on arguments.
In case of VARCHAR data type, DATE_ADD() reported "binary" character set,
which was wrong.
Fix: make DATE_ADD() return @character_set_connection in VARCHAR context.

@ sql/item_strfunc.cc
- Moving code from Item_str_ascii_func::val_str() to
Item_str_func::val_str_from_val_str_ascii(), as
this code needs to be shared by Item_date_add_interval.
- Adding str2 parameter to be used as a buffer, instead of
using private ascii_buf member.
@ sql/item_strfunc.h
- Moving code from Item_str_ascii_func::val_str() to
Item_str_func::val_str_from_val_str_ascii()
- Removing "String *val_str_convert_from_ascii(String *str, String *ascii_buf)"
prototype as it was neither used nor declared.
@ sql/item_timefunc.h
- Overwriting parent's charset_for_protocol() method,
becase we need to behave differenlty in VARCHAR and DATE/DATETYPE context.
- Adding ascii_buf for conversion.
- Adding val_str_ascii() prototype.
- Adding val_str() which uses newly added
Item_str_func::val_str_from_val_str_ascii(),
passing ascii_buf as a conversion buffer.
