MDEV-13384: "window" seems like a reserved column name but it's not listed as one

Browse Source 
Window is a reserved keyword according to SQL Standard 2016. However, we
can make the grammar slightly flexible by allowing WINDOW keyword everywhere
except table aliases. Change yacc grammar to separate between all keywords
and table_alias keywords.
