Changing the rest of the simple CSSValue subclasses to the oilpan transition types.

Only CSSPrimitiveValue and CSSValue remains.
I also had to remove an assignment operator in RawPtr and  make a constructor explicit to avoid ambiguity.
Finally added WTF_MAKE_FAST_ALLOCATED_WILL_BE_REMOVED which expands to nothing when oilpan is enabled and
WTF_MAKE_FAST_ALLOCATED when refcounting is enabled.

Refactor SVGPreserveAspectRatio::parseInternal()

This cl removes "goto" and replaces it with local variables, and fixes poor coding style.

[DevTools] Do not recursively save sizes of all inner sidebars.

This allows user to resize outer splitview freely, while inner
splitviews accomodate to the saved preference.
For example, making DevTools window temporary very small
and then resizing it back will not reset all user-set sidebar sizes.
