[libc++] Systematically define a macro to check whether a feature is unavailable

Browse Source 
Previously, we inconsistently defined whether a feature was unavailable
on a given deployment target. We would have availability attributes for
all features, but only some features had the equivalent of a _HAS_NO_FOO
macro in the form of the DISABLE_FTM___foo macros. Instead, systematically
define a _HAS_NO_FOO macro, which makes it easier to understand how to
add availability markup for a new platform.

//
// This mechanism is general in nature, and any vendor can add their markup to
// the library (see below). Whenever a new feature is added that requires support
// in the shared library, a macro should be added below to mark this feature
// as unavailable. When vendors decide to ship the feature as part of their
// shared library, they can update the markup appropriately.
// in the shared library, two macros are added below to allow marking the feature
// as unavailable:
// 1. A macro named `_LIBCPP_AVAILABILITY_HAS_NO_<feature>` which must be defined
// exactly when compiling for a target that doesn't support the feature.
// 2. A macro named `_LIBCPP_AVAILABILITY_<feature>`, which must always be defined
// and must expand to the proper availability attribute for the platform.
//
// When vendors decide to ship the feature as part of their shared library, they
// can update these macros appropriately for their platform, and the library will
// use those to provide an optimal user experience.
//
// Furthermore, many features in the standard library have corresponding
// feature-test macros. When a feature is made unavailable on some deployment
// target, a macro should be defined to signal that it is unavailable. That
// macro can then be picked up when feature-test macros are generated (see
// generate_feature_test_macro_components.py) to make sure that feature-test
// macros don't announce a feature as being implemented if it has been marked
// as unavailable.
// feature-test macros. The `_LIBCPP_AVAILABILITY_HAS_NO_<feature>` macros
// are checked by the corresponding feature-test macros generated by
// generate_feature_test_macro_components.py to ensure that the library
// doesn't announce a feature as being implemented if it is unavailable on
// the deployment target.
//
// Note that this mechanism is disabled by default in the "upstream" libc++.
// Availability annotations are only meaningful when shipping libc++ inside
