LibGfx: Add rounded_int_rect() function for Rects

Browse source 
We were seeing a problem in LibWeb, where layout elements would be 1px
larger than they should be, due to layout positions using float values,
and then converting using `enclosing_int_rect()`. `rounded_int_rect()`
replaces that use, by maintaining the original rect's size.
