vkd3d-shader/hlsl: Pass a vkd3d_shader_source_list pointer to hlsl_ctx_init().

Browse Source 
Instead of storing the list inside struct hlsl_ctx. The source file
names in the list are used by the location information that the HLSL
frontend produces, and end up being referenced by the vsir program. If
we want the vsir program to be able to outlive the hlsl_ctx, its
location information can't reference data owned by the hlsl_ctx.
