Bug 1845228: Make Mahara work with mysql 8.0.17

-Add mysql reserved words 'array' and 'member'
-Remove deprecated ||, &&, ! and replace with OR, AND, NOT
Note: Use of || is deprecated unless the PIPES_AS_CONCAT SQL mode is
enabled. In that case, || signifies the SQL-standard string
concatenation operator
-Quote uses of member in SQL queries
Note: when passed in as a variable it is quoted on query construction
