Moved param initialization into finalize() in the Canvas WPT generator
Before this CL, the variant grid's params was initialized the first
time the grid's params property was used. This implicit
initialization was confusing because it meant we had to first use
params at the exact right time. Using it too soon was a bug (before
the variant's expected_img param is configured for instance).
This CL moves the grid's param creation into the finalize() method,
removing this confusion.
