BUG #46572 DROP TEMPORARY table IF EXISTS does not have a consistent behavior in ROW mode

In RBR, 'DROP TEMPORARY TABLE IF EXISTS...' statement is binlogged when the table
does not exist.
      
In fact, 'DROP TEMPORARY TABLE ...' statement should never be binlogged in RBR
no matter if the table exists or not. 
This patch addresses this by checking whether we are dropping a
temporary table or not, when building the custom drop statement.
