opencl-clang-19 depends on llvm-toolchain-19 but the goal is to not
include llvm 19 in forky. The default llvm in forky currently is 21. I
see that opencl-clang-21 is not yet in Debian. On the other hand,
opencl-clang-19 does not appear to have any reverse dependencies. I
think it's safe to remove it from Testing, but maybe it is needed in
either Unstable or Experimental for now for bootstrapping newer
versions of opencl-clang.

Thank you,

This package should be removed from testing along with llvm-toolchain-19.
