canvas: Properly bound all image pattern axis by inserting clip (#37668)

Browse source 
Before we only handled no-repeat for rect, this means we rendered
https://sagudev.github.io/briefcase/no-repeat.html incorrectly (like
firefox). Now if one of the axis is bounded (does not repeat) we clip it
and let other axis be unbounded (technically we clip it to end of
canvas).

This is also needed for vello backend.

Testing: Tests in WPT exists and another test is added.
