vkd3d-shader/spirv: When declaring a CBV initialise the register with the register index range.

The declaration instruction register contains id, range first, and range
last. The backend includes range first in the variable name. After commit
e8b3561252 it was always zero, and since commit 67f0196c33 it is
UINT_MAX, so constant buffers are named, e.g., "%cb0_4294967295".
