Length CSSPrimitiveValue::resolveAsLength() casts to double then Length casts
to float

Reviewed by Sam Weinig.
236687@main added a `clampTo<double>()` in `CSSPrimitiveValue::computeLength()`
in order
to avoid a compiler warning about int-to-float conversion of
`maxValueForCssLength`. However,
Length stores a float internally, and its constructor does a static_cast<float>
of the argument.
So let's just convert directly to floats.
`minValueForCssLength` and `maxValueForCssLength` become floats, and callers of
the Length
constructor that takes a float now use `clampTo<float()`.
`maxValueForCssLength` can't be losslessly converted to a float; ideally we'd
round down to
the next representable float (rather than to the nearest), but that can't be
done at compile
time unless we just hardcode the float value, so stay with static_cast<float>
for now.
