pcem: avoid dynamic offsetof in Voodoo codegen

The Voodoo x86 code generators compute offsets into array members
with offsetof(type, field[index]). Some compilers reject that
expression form.

Add helpers that derive the offset from field[0] plus an element
stride. That preserves the generated offsets without relying on a
runtime-indexed offsetof expression. This matches the same cleanup
merged upstream in 86Box.
