Unrolled build for rust-lang#131088

Rollup merge of rust-lang#131088 - klensy:llvm-terminfo, r=Kobzol

add fixme to remove LLVM_ENABLE_TERMINFO when minimal llvm version is 19

`LLVM_ENABLE_TERMINFO` was removed in llvm 19: https://github.com/llvm/llvm-project/blob/release/19.x/llvm/docs/ReleaseNotes.rst#changes-to-building-llvm; current minimal llvm is 18, so left fixme here.
