Automatic update from web-platform-tests
Support number producing css math functions in ConvertScale

Currently, StyleBuilderConverter::ConvertScale directly calls
GetDoubleValue() which is incorrect for math functions, rewrite it
to use ComputeNumber with CssToLengthConversionData instead.

Note: the crash is due to the parse time percent resolution in
ConsumeNumberOrPercent, which doesn't work with math functions yet.
It will be fixed in the following CL, meanwhile the added test case
covers the changed functionality.
