LOG: [gn build] add asan runtime on linux and mac
This produces a seemingly-working dynamic (x64-only) asan dylib on macOS
and static libraries on Linux.
I've had this sitting in a branch for a long time and wanted to get
check-asan working before landing it, but smaller patches and fewer
local branches is probably better.
