[libc++][Android] Mark tests XFAIL/UNSUPPORTED (#69271)
Mark tests as necessary to accommodate Android L (5.0 / API 21) and up.
Add three Android lit features:
- android
- android-device-api=(21,22,23,...)
- LIBCXX-ANDROID-FIXME (for failures that need follow-up work)
Enable an AIX workaround in filesystem_test_helper.h for the broken
chmod on older Android devices.
Mark failing test with XFAIL or UNSUPPORTED:
- Mark modules tests as UNSUPPORTED, matching other configurations.
- Mark a gdb test as UNSUPPORTED.
- XFAIL tests for old devices that lack an API (fmemopen).
- XFAIL various FS tests (because SELinux blocks FIFO and hard linking,
because fchmodat is broken on old devices).
- XFAIL various locale tests (because Bionic has limited locale
support). (Also XFAIL an re.traits test.)
- XFAIL some print.fun tests because the error exception has no system
error string.
- Mark std::{cin,wcin} tests UNSUPPORTED because they hang with
adb_run.py on old devices.
- Mark a few tests UNSUPPORTED because they allocate too much memory.
- notify_one.pass.cpp is flaky on Android.
- XFAIL libc++abi demangler test because of Android's special long
double on x86[-64].
N.B. The `__ANDROID_API__` macro specifies a minimum required API level
at build-time, whereas the android-device-api lit feature is the
detected API level of the device at run-time. The android-device-api
value will be >= `__ANDROID_API__`.
