mesa/st: Reuse st_choose_matching_format from st_choose_format().
We had this ad-hoc exact size matching for unsized internalformats, but st_choose_matching_format() can do exactly what we want. This means, that, for example, we'll now prefer the matching ordering for 565/565_REV if the driver supports both orders. We also pass Unpack.SwapBytes through from ChooseTextureFormat so that we can hit the memcpy path for 8888 formats when that flag is set. Some interesting format choice changes from this (on softpipe): intf/form/type before after ---------------------------------------------------- RGBA/RGBA/USHORT: R8G8B8A8_UNORM -> RGBA_UNORM16 RGB/RGBA/8888: X8B8G8R8_UNORM -> R8G8B8X8_UNORM RGB/ABGR/8888_REV: X8B8G8R8_UNORM -> R8G8B8X8_UNORM RGBA/RGBA/5551: B5G5R5A1_UNORM -> A1B5G5R5_UNORM RGBA/RGBA/4444: R8G8B8A8_UNORM -> A4B4G4R4_UNORM RGBA/GL_RGBA/1010102: R8G8B8A8_UNORM -> A2B10G10R10_UNORM DEPTH/DEPTH/UINT: Z24X8 -> Z_UNORM32 DEPTH/DEPTH/USHORT: Z24X8 -> Z_UNORM16 v2: Make sure that the baseformat still matches. v1 would pick MESA_FORMAT_L16_UNORM for RED/LUMINANCE/SHORT, when we clearly want a red format.
