nir: Offset vertex_id by first_vertex instead of base_vertex
base_vertex will be zero for non-indexed calls and in that case we
need vertex_id to be offset by the ‘first’ parameter instead. That is
what we get with first_vertex. This is true for both GL and Vulkan.
The freedreno driver is also setting vertex_id_zero_based on
nir_options. In order to avoid breakage this patch switches the
relevant code to handle SYSTEM_VALUE_FIRST_VERTEX so that it can
retain the same behavior.
v2: change a3xx/fd3_emit.c and a4xx/fd4_emit.c from
SYSTEM_VALUE_BASE_VERTEX to SYSTEM_VALUE_FIRST_VERTEX (Kenneth).
