Set the initial text value of wxSpinCtrlGeneric correctly.

The text control was left empty if the string value was not specified, but
it should use the numeric initial value instead in this case.

This notably affected wxSpinCtrlDouble under non-GTK platforms.

Closes #16621.

Fix best size calculation for buttons with bitmaps in wxMSW.

Add the bitmap margins to the bitmap size, not the total button size.

This fixes the buttons becoming unnecessarily tall as soon as they were
assigned even a tiny bitmap.

Re-add wxFD_OVERWRITE_PROMPT and wxFD_FILE_MUST_EXIST to wxGenericFileDialog.

Support for these styles was accidentally removed in r48733, re-add them back.

Fix size of the icon returned from wxFSVolume::GetIcon().

Calling SetHICON() is not enough, the icon size already needs to be set or,
even better, CreateFromHICON(), which does both atomically, should be used.

Closes #16672.
