Add ASan and UBSan options (#6825)

Browse source 
When we need to enable ASan/UBSan in PHP extension, we also need to enable it in PHP kernel. Providing these options makes it easier for us to enable ASan/UBSan when compiling PHP.
And we use --enable-address-sanitizer and --enable-undefined-sanitizer in azure-pipelines.yml instead of changing CFLAGS manually.
We also add compile flag check to MSan.
