[clang-tidy] Refactor the code and add a close-on-exec check on memfd_create() in Android module.
Summary:
1. Refactor the structure of the code by adding a base class for all close-on-exec checks, which implements most of the needed functions.
2. memfd_create() is better to set MFD_CLOEXEC flag to avoid file descriptor leakage.
