MCGR: Adaptions to WriteGradientFill and BGradient

Added code to make WriteGradientFill directly use the
available BGradient implementation. The goal is to
never directly work on awt::Gradient2, but use
BGradient & it's tooling methods.

Added constructors and tooling to BGradient and
BColorStops to make that easier (single line
conversions between uno::Any, basesgfx classes
and awt:: incarnations). Directly handle uno::Any
and awt:: classes, changed stuff to make use of
this.
