Split SVG1DOM counter further

Split all counters relating to basic data types into smaller
parts. Use MeasureAs when these interfaces are implemented by multiple
other interfaces. Using Measure for them would give a lot of
unnecessary UseCounters. It seems more likely that we try to remove
interface methods in its entirety than splitting the interface, moving
some and removing some.

Also remove the counter from constants in affected interfaces. If we
get to remove the interfaces where the constants are used, they can go
too. Otherwise they likely have to stay.
