Port Address Sanitizer

[kateinoigakukun]

After spending 2 weeks, we got an initial port for ASan on Wasm/WASI, working with some apps on my local machine.
This ticket is to track its upstreaming work and make it available for everyone

• Swift
  • [wasm] Add WASI as a supported target for sanitizers swiftlang/swift#81197
  • IRGen: Disable ASan for the auto dynamic replacement array swiftlang/swift#81348
  • Distribute libclang_rt.asan.a as a part of Swift SDK
  • Distribute ASan-enabled wasi-libc, libcxx, libswiftCore as a part of Swift SDK
• LLVM
  • [DNM][clang] Support ASan on WASI swiftlang/llvm-project#10578
  • [clang] Support ASan on WASI llvm/llvm-project#139014
  • [ASan] Recognize WASI platform in sanitizer_platform.h llvm/llvm-project#139017
  • Add a compiler-rt build option to disable shared libraries for sanitizers
• WebAssembly
  • Rename libc function names with alias hack to allow ASan to intercept calls
    • malloc, free, and other allocator function family
    • memset
    • memcpy
