docs: reflect that all 13 VU1 renderers build with openvcl + masp

Previously CMAKE_BUILD.md claimed only 11 of 13 renderers compiled with
openvcl, listing `indexed` and `scei` as incompatible. Both now build
cleanly with openvcl + masp, as confirmed by build-test/vu1/ containing
all 13 .vo artifacts produced by the open pipeline.

Also remove the commented-out skip block in CMakeLists.txt that used
to fall back to pre-built objects for those two renderers. The fallback
to pre-built .vo files via the outer if/elif/else for VU1 tools is
preserved (still useful on hosts without the toolchain installed).
