wxMSW: Use TBSTYLE_AUTOSIZE for toolbar buttons with horizontal text.

Without this style, all buttons share the same width and look ugly when
their labels differ even a little in their lengths. With
TBSTYLE_AUTOSIZE, toolbar buttons use the size of their image plus
label's width and look better, even though their sizes differ.
