Fix display of figure window mouse cordinates using wx python backends. Label text requires an initial size to be given to have none zero dimensions in toolbar.

Does the patch at #22014 (comment) (plus version gating to only do it on Windows) not work for you? That would seem better than hardcoding a size... |

I'd not seen the bug report until submitting my fix (check list made me
check).
However it seems unnecessarily complex and the events behaviour can be
different between platforms hence it not working properly on GTK.
I've tried that code on windows11 and it partially works - but only after a
window resize - the coordinates show in the middle until resized.
As this bug has been present since 2021 i think the simple fix is ok (never
let perfect be the enemy of good) it will restore functionality thats been
broken for some time and I suspect (although I've not had a chance to
check) that the reason it currently works on GTK but not Windows is exactly
that the StaticText controls default size is non-zero!

Fix display of figure window mouse coordinates using wx python backends.
Currently the mouse coordinates are not visible when using the wx python backend.
This sets an initial size to the text control used to display the coordinates currently the width is set to 0 when NavigationToolbar2Wx.Realize() is called as there is no label text specified and no size defined.
Setting an initial size of (120,-1) should work for most systems unless the font size is very large.
Alternatively NavigationToolbar2Wx.Realize() can be called in NavigationToolbar2Wx. set_message() after the label text is set so that space in the toolbar is allocated however this causes flickering.
I found a related bug [Bug]: wx + windows draws mouseover cursor text beyond the toolbar's extents #22014
closes #22014
