LOG: [compiler-rt] Fix asan_interceptors.cpp build warning -Wunused-template (#209750)

mmap_interceptor/munmap_interceptor template functions are instantiated
in sanitizer_common_interceptors.inc only under `#if
SANITIZER_INTERCEPT_MMAP`. Fix `unused function template
'mmap_interceptor'` warning on Windows, which is error under -Werror.
