This looks great, but can we make it just do-the-right-thing and get rid of the
nerd knobs (i.e no meson configure).

The address sanitizer already has a way to detect if enabled.

GCC uses:
__SANITIZE_ADDRESS__

Clang uses:
#if defined(__has_feature)
#  if __has_feature(address_sanitizer)

Tried this method you said. It can run successfully. Because gcc and clang have different
Methods for determining whether to turn on the asan function, so if you judge the two
methods in the code, it feels not simple to judge in meson.
