[graphite] Check miter limit for stroked rects
I had a flawed understanding of the miter limit and thought it's min
allowed value was sqrt(2) so 90 degree corners would never be a bevel.
That's not the case so this checks the miter limit before uploading the
final join style to the instance data.
I also noticed that the stroke_rect_shader GM was setting the miter
limit on the paint and then drawing a second row, so on the second
time through the original full-miter draw was still seeing the very
small miter limit and was becoming beveled. This is fixed so the
miter column matches across AA and non-AA.
I confirmed that in Graphite, the beveled-miter column now draws with
bevels instead of mitered.
