Make various circled operators bigger

It was very hard to tell apart U+2295 CIRCLED PLUS and U+233E APL
FUNCTIONAL SYMBOL CIRCLE JOT.  Making the circles the size of an
upper-case 'O' has helped with that.  I've enlarged U+2296 CIRCLED
MINUS and U+2299 CIRCLED DOT OPERATOR to match.  I've left U+25CB
WHITE CIRCLE alone because it probably wants to be distinct from
upper-case 'O' and it doesn't have anything in it.
