uxtheme/tests: Add EnableThemeDialogTexture() tests.

These tests show that DefDlgProcA/W() are hooked to implemented dialog theming, using a pattern
brush created from the tab body part. For dialogs that need theming, EnableThemeDialogTexture(ETDT_USETABTEXTURE)
or EnableThemeDialogTexture(ETDT_USEAEROWIZARDTABTEXTURE) is called for the dialog. And then
static or button controls in comctl32 v6 call EnableThemeDialogTexture(ETDT_ENABLE) to activate it.
A WM_ERASEBKGND is also needed to activate dialog theming. test_WM_CTLCOLORSTATIC() in dlls/comctl32/tests/static.c
doesn't send this message after EnableThemeDialogTexture() calls, which misdirected me to think that
DefDlgProcA/W() are not hooked.
