d3d10umd, meson: Allow naming d3d10umd DLLs

For graphics drivers on windows it is beneficial to have usermode DLLs
names matching driver overall name, example being vm3dum_10.dll and
nvwgf2um.dll for d3d10 usermode drivers from VMWare and Nvidia.

To implement that new meson option `gallium-d3d10-dll-name` that
names the resulting d3d10umd target DLL is introduced. Additionaly,
to avoid confusion `gallium-dll-name` is renamed to `gallium-wgl-dll-name`
as it corresponds to the name used in wgl target.
