Refactor createImageBitmap resize layout tests

This change reduces createImageBitmap resize test tolerance from 10 to 0
for all image sources except for blob (which is set to 5).
It also refactors the tests to include pixelated, low and medium filter
qualities. Furthermore, it separates the test path for premul and unpremul
image bitmap sources when the filter quality is high, to match the way this
is implemented in chromium.
