The libcs we use don't need these any more (if they ever did), and we
were setting these globally in the build system anyway.
Also remove the -D_LIBCPP_ENABLE_CXX17_REMOVED_BINDERS from versioner
which doesn't seem needed any more either.

* When calculating the required guard, if a per-arch `introduced`
value is less than the arch min-API, drop the per-arch guard (i.e.
reset the value to 0). This is needed for RISC-V, where we don't
parse the headers with Clang, because the highest APIs we compile
for (e.g. 23, 34) are less than the current RISC-V min API of 10000.
Resetting it to 0 here means we don't need this optimization while
generating an arch-set guard. (i.e. We don't need to calculate
max_min_version. That code should have been calculating a
"min_min_version" anyway.)
* Remove the broken all-supported-archs entry from arch_sets. It has a
few problems:
* It's redundant with the "global availability" code path above,
which is used when the declaration has no per-arch annotations.
* If this code path runs, then we generate two more guard
expressions, for !LP64 and LP64.
* Passing "" to generate_guard is broken for a non-zero version,
and for a zero version, adding an empty string to `expressions`
breaks if the vector has 2 or more expressions.
(I think consolidating per-arch info, e.g. using a single check for
__INTRODUCED_IN_32(40) __INTRODUCED_IN_64(40), is a nice idea, but
it should happen as a natural consequence of removing the
arch-independent "global availability" info in favor of always
tracking it per-arch.)
* Rewrite the arch-set guard generation. Add an optimization so that
the (__ANDROID_API__ >= N) guard for __INTRODUCED_IN_64(N) is still
useful for RISC-V as long as N is small enough. (Currently we're
checking that N is <= 10000.)
This change fixes the "preprocessor" test that run_tests.py runs. The
"slow_preprocessor_idempotence" test is still broken.

Unlike the kernel script (where plain "riscv" was correct because that's
what the kernel uses, making no distinction between riscv32 and riscv64
in the uapi header directories), this should say "riscv64" because
that's what our build system uses.
(This wasn't caught because we haven't wired up the .bp file yet.)

This commit adds versioner_fortify_inline annotation. This annotation
indicates that the annotated function is an overloaded inline function
for _FORTIFY_SOURCE implementation. They are usually enabled/disabled
by the enable_if attribute, thus the versioner don't have to check
whether they have conflicting definitions.
