vkd3d-shader: Dump shaders as soon as possible.

So that they are dumped even if parsing fails, which is a circumstance
in which one likely wants to see the problematic shader.

The downside of that is that for shader types other than HLSL
the profile is not written any more in the filename. This should
not be a big problem, because in those cases the shader describes
its own type.

When dumping an HLSL shader, the id is brought in front of the profile
in the file name, in order to make it more tab-friendly: when dealing
with a directory full of shaders it's likely that the id determines
the profile, but the other way around.
