VCLUnoHelper: Align AWT <-> VCL helpers with convert.hxx impl

There are currently (at least) 2 sets of helpers
for converting from AWT to VCL point, rectangle
and size classes - and the other way around:

* the ones in `include/toolkit/helper/convert.hxx`
* the ones provided by `VCLUnoHelper`

Align the `VCLUnoHelper` implementations with the
ones in `include/toolkit/helper/convert.hxx` and
make them inline as well.

Switch params from the specific subclasses to the
more generic base classes as well
(e.g. `css::awt::Point` -> `PointTemplateBase`).

Otherwise, `VCLUnoHelper::ConvertToVCLRect` is the only one
that didn't implement the functionality in the
exact same way as the counterpart, `VCLRectangle`,
as it was manually calculating the right and bottom
edges.

The `VCLRectangle` implementation
gives the same result for valid rects, so take over
that one. (It shouldn't make a difference for the
only 2 current callers, `ControlHolder::getPosSize`
and `VCLXGraphics::clear`.)

This commit is in preparation of consolidating all uses
to use the `VCLUnoHelper` variants and getting
rid of the other one in following commits.
