[xfa] Cover CFWL_MonthCalendar as part of embedder tests

Precise clicks in a date time picker plus rendering the page in
the intermediate states is required to draw the calendar, pick
a date, and stuff that date into the field.

-- Tests hobbled by cross-platform font issues.
-- Confirmed dumped images on local platform.
-- Add cpwl_edit.h to correspond test per style guide.
