Set up the DC passed to wxDataViewCustomRenderer::Render() to use the font and
colour defined by the item attribute by default so that any calls to
RenderText() from it will use them automatically.
Also added public wxDataViewCustomRenderer::GetAttr() to allow retrieving the
attribute explicitly in Render().
The column using custom renderer in the dataview sample now works as expected
in the generic version; the native ones will be corrected in the upcoming
commits.

This method is useful for getting the number of items in the control and
should be part of the public API instead of being marked as internal.
Closes#11380.

This is an incompatible change but having to use a non-const model pointer to
call a clearly logically const version was simply too ugly so change it while
we still can.

Old code created the tree model and its unique built-in column only in
wxDataViewTreeCtrl ctor but not in Create(), meaning that the behaviour was
very different depending on whether you used base class ctor call or Create()
in a derived class. This was confusing and completely inconsistent with wx API
in which using the default ctor and Create() is supposed to always have
exactly the same effect as using non-default ctor so change this to create the
model in Create() so that it's always done.
Slightly update the documentation and also add wxDataViewTreeCtrl::Init() for
consistency.

This method allows to simply test whether we have a value at the given row and
column or not (as it happens for container items unless they too have columns).
Currently this method is not virtual and is not used by the implementations
yet but it might make sense to make it virtual and allow overriding it in the
future.

ChangeValue() is a trivial wrapper calling both SetValue() and ValueChanged().
It allows to replace many calls to SetValue() immediately followed by
ValueChanged() with a single function call which is significantly shorter and
less error-prone (e.g. most of the existing code didn't test SetValue() return
code at all).

Implemented ellipsization in the generic, GTK and both OS X Carbon and Cocoa
versions but it currently doesn't work well in GTK as it changes the item
alignment unconditionally, this will need to be fixed later.
The behaviour for the columns is currently inconsistent between ports too:
under MSW they (natively) use wxELLIPSIZE_END, under GTK -- wxELLIPSIZE_NONE
and under OS X the same ellipsization mode as the column contents, i.e.
wxELLIPSIZE_MIDDLE by default.

There is no reason to have a separate class for rendering the text honouring
the attributes defined for it, wxDataViewTextRenderer itself already does this
perfectly well.
