Change return type of PrintPage

PrintPage should not return a bool parameter. The return type has been changed to void.

To keep it compatible with the blink code, old function has been kept.

This change will involve a total set of five patches. This is patch 1 from the
below list.

1. Chromium side with two functions, one with old bool return type and other
with three parameter but with void return type. 
2. Blink side with old bool return function plus a function with void return
type and an additional third parameter.
3. Chromium side with two functions with different parameters, return type is
not changed. One function that removes third parameter added in first CL and
other function keeping the third parameter.
4. Blink side remove function with three parameters. 
5. Chromium side remove function with three parameters.

I think this plan looks good.

+cc piman and creis, could you review this? I incorrectly asked Habib to do this
in 3 patches but because we're changing a return type this isn't possible.
