  [clang] Support ASan on WASI (#139014)

I'm working on porting ASan to Wasm/WASI targets, and this is the first
part of the change sets. I'll post runtime changes separately.

This change makes `-fsanitize=address` available for WASI target by
replicating what we do for Emscripten because they share the same memory
model.
