ANDROID: gki_defconfig: cfi: unconditionally normalize integers

Browse Source 
The -fsanitize-cfi-icall-experimental-normalize-integers flag must be
passed to clang for it to be possible to use Rust in the kernel when CFI
is enabled. However, only passing this flag when CONFIG_RUST is enabled
is undesirable because it affects the ABI of C code.

Enabling the flag unconditionally allows us to toggle CONFIG_RUST
without having it change the ABI of existing C code. This helps prevent
b/350371019 from happening again in the future.
