Auto merge of #9109 - nerith:createpattern, r=jdm

Support empty strings as the repeat argument (CreatePattern)

According to the third step in the specification [1], createPattern
should let the repetition argument be "repeat" when it is the empty
string.

The code in CanvasRenderingContext2D::CreatePattern did not implement
this step and instead threw a SyntaxError exception when an empty
string was supplied as the repetition argument.

Fixes #9079.
