A cleanup for MDEV-12172: Fixing "mtr --suite=compat/oracle" test failures

Adding missing commands into sql_yacc_ora.yy:

%token  VALUES_IN_SYM
%token  VALUES_LESS_SYM

and their parser hacks with Select->parsing_place.

Note: the grammar for table_value_constructor will be merged later separately.
