[libc][cmake] Tidy compiler includes (#66783)
We want to activate `llvm-header-guard` (#66477) but the current CMake
configuration includes paths that should be `isystem`. This PR restricts
the number of `-I` passed to the clang command line and correctly marks
the llvm libc include path as `isystem`.
