[PATCH vkd3d 2/5] vkd3d-shader/hlsl: Set the source name in hlsl_ctx_init().

[Henri Verbeet]

Without this, HLSL compiler messages were missing the source name. For
example, when attempting to compile gears.hlsl from the "gears" demo
with vkd3d-compiler:

":33:17: E5000: syntax error, unexpected NEW_IDENTIFIER"
