Don't enable CFI diagnostics in include paths.

Don't enable CFI diagnostics by default when applying it in include
paths. Part of a broader effort to remove diagnostics mode from CFI
across the board.

This should reduce performance overhead and also allows the minimal
runtime to work when other ubsan sanitizers are enabled. CFI stack
dumps should include a CFI related function, so it should be apparent
when a crash is CFI-related.
