[llvm] [IN PROGRESS] Fix premerge script so certain projects appear in LLVM_ENABLE_RUNTIMES. (PR #145754)

[Amy Huang via llvm-commits]

https://github.com/amykhuang created https://github.com/llvm/llvm-project/pull/145754

Putting libc in "LLVM_ENABLE_PROJECTS" instead of "LLVM_ENABLE_RUNTIMES" is deprecated.
The script has some logic already for doing this correctly but libc was still appearing in LLVM_ENABLE_PROJECTS.
