Subject: [PATCH] [Support] Remove terminfo dependency
The terminfo dependency introduces a significant nonhermeticity into the
build. It doesn't respect `--no-undefined-version` meaning that it's not
a dependency that can be built with Clang 17+. This forces maintainers
of source-based distributions to implement patches or ignore linker
errors.
Remove it to reduce the closure size and improve portability of
LLVM-based tools. Users can still use command line arguments to toggle
color support expliticly.
Fixes #75490
Closes #53294 #23355
