[libc++] Silence CMake's install messages in the CI

[philnik777]

Currently, there are a ton of -- Installing: and -- Up-to-date: messages in the CI log, which just clutter the output. This disables these messages to significantly shorten the CI logs, making them much faster to load and easier to read.
