This patch aligns and simplify SVG Paint Server handling as per web 
specification [1]:

"If a paint server reference in a <paint> is invalid, and no fall-back value is 
given,
no paint is rendered for that layer."

&

"The value none is a fallback value to use if the paint server reference in the 
layer
is invalid (due to pointing to an element that does not exist or which is not a
valid paint server)."

This also syncs WPT from upstream for "fill-fallback-invalid-uri" test:
