XML processor generates invalid code for printf style formatting

[dalewking]

If you have a string that has printf format specifiers like:

    <string name="total_duration">%1$s Total</string>

It generates:

    override val totalDuration = { p0: String -> 
        "%s Total"
            .format(p0)
    }

Problem is there is no such format method on string at least in common code.

For most simple cases you could simply generate string interpolation code and if the format specifier is more complex generate warnings

I confirmed that our string files do not do anything more complicated than %1$s or %1$d so simple string interpolation is all we need.
