[D3D] Some texture enumeration 'fixes'

[Lionel Ulmer <lionel.ulmer@free.fr>]

As usual, Windows games only expect ARGB textures (and do not even bother to
check the bitmasks). So, as for the 'packed' texture formats, enumerate only
the 32 bpp ARGB format.

Changelog:
 - only enumerate 32 bpp ARGB texture format and remove RGBA one
 - add support for 32 bpp ARGB texture format
