We need an alpha mask, even if it is totally opaque, so that
drawinglayer::primitive2d::ProcessAndBlurAlphaMask() can be called.
Otherwise, blurring of edges will fail in cases like running in a
slideshow or exporting to PDF.

When the Primitives for the Glow-Effects were added
(modified ShadowPrimitive2D, SoftEdgePrimitive2D and
GlowPrimitive2D) a modified version of impBufferDevice
was created and used. That lowered the speed for
drawing objects with transparence by about factor 2.5
and was unfortunately not only done for these
Primitives, but for transprent objects in general.
For the mentioned factor refer to:
Patch to demonstrate former and now repaint differences
https://gerrit.libreoffice.org/c/core/+/129301
After having reworked those Primitives to use another
mechanism and being decomposed so they will work in all
now and future renderers, it is possible to go back to
that easier and faster method to render Transparency.
For extended information, please take a look at the
added comments, mainly in vclhelperbufferdevice.hxx
Identified a still bad behaviour when objects use a
TransparenceGradient. Corrected that and added (at
this opportunity) a method 'createAlphaMask' along
with 'convertToBitmapEx' which is now used in the
GlowPrimitive2D & ShadowPrimitive2D which only need
the AlphaMask to do their job anyways (I had commented
there that thjis is possible before). That will
be faster for visualizing those Primitives.

Rather than make all the BasePrimitive2D classes bear the cost of being an UNO
object, we just wrap the top level BasePrimitive2D in this class when we need
to pass them over UNO.
This reduces the locking overhead when doing normal drawinglayer operations,
and reduces the size of drawinglayer objects and the cost of initialising
them, which shaves 5% off the load/display time of a large barchart.
Add new drawinglayer::convertPrimitive2DContainerToBitmapEx utility
method to avoid needing to convert to Sequence<XPrimitive2D>

Look for places where we can pass Primitive2DContainer by move reference
and so avoid unnecessary copies.
