[SP] Add flag to explicitly disable slimming paint by default when running layout tests.

[SP] Add flag to explicitly disable slimming paint by default when running layout tests.

Note this is a no-op until we submit http://crrev.com/1169193003 to
add the notion of a '--disable-slimming-paint' flag. By submitting
this first, we ensure that the current state of LayoutTest
expectations will continue to pass after we flip the slimming paint
default.
