cmake : add sanitizer flags for llama.cpp (#11279)

* cmake : add sanitizer flags for llama.cpp

ggml-ci

* tests : fix compile warnings

ggml-ci

* cmake : move sanitizer flags to llama_add_compile_flags

ggml-ci

* cmake : move llama.cpp compile flags to top level lists

ggml-ci

* cmake : apply only sanitizer flags at top level

ggml-ci

* tests : fix gguf context use in same_tensor_data

* gguf-test: tensor data comparison

* dummy : trigger ggml-ci

* unicode : silence gcc warnings

ggml-ci

* ci : use sanitizer builds only in Debug mode

ggml-ci

* cmake : add status messages [no ci]
