These tests execute php.exe without passing the PATH, what might be a more general issues, but at least with ASan enabled, the required DLLs could usually not be found, resulting in the tests stalling. Closes GH-17079.
As is, whenever `proc_open()` needs to invoke the shell, cmd.exe is looked up in the usual executable search path. That implies that any cmd.exe which is placed in the current working directory (which is not necessarily what is reported by `getcwd()` for ZTS builds), will be used. This is a known attack vector, and Microsoft recommends to always use the fully qualified path to cmd.exe. To prevent any cmd.exe in the current working directory to be used, but to still allow users to use a drop in replacement for cmd.exe, we search only the `PATH` for cmd.exe (and pass the fully qualified path to `CreateProcessW`), instead of relying on automatic executable search by passing the base name only. To be able to easily test this, we provide a minimalist C file which will be build as test_helper, and used by the new test case.
