fanzha02 3ee426aefa cmd/dist: add asan tests in misc/cgo/testsanitizers package
Add asan tests to check the use of Go with -asan option.

Currenly, the address sanitizer in Go only checks for error
memory access to heap objects.

TODO: Enable check for error memory access to global objects.

Updates #44853.
