build: remove support for gyp

Upstream GYP has been unmaintained for some time now. The only big
downstream user is Node.js and they already maintain GYP build files
for their other dependencies.

This commit removes vcbuild.bat because:

1. it's entirely built around GYP, and
2. duplicates a lot of functionality that cmake provides out of the box

This commit also removes appveyor.yml. It hasn't been used after we
stopped providing prebuilt binaries for Windows about two years ago.

As if that isn't enough, this commit also removes the Android build
scripts. They were wrappers around GYP. Use CMake.

aix: Fix broken cmpxchgi() XL C++ specialization.

The preprocessor was used to select a special implementation when
building on AIX using XL C++ (strangely, not XL C). This code
implemented `cmpxchgi()` by directly reading the old value and then
calling `__compare_and_swap()`, an intrinsic that does not provide
any sort of memory barrier guarantees. The return value was not
used, and the value read prior to the `__compare_and_swap()` call
was returned. There is no way that this code could provide the
required semantics of the function and it causes observable data
races and strange library failures in production under load.

XL C/C++ for AIX has provided support for the GCC intrinsic used in
the GCC/Clang cases since version 12.1 of the compiler. This
version of the compiler is old enough that it doesn't warrant a
version check. (The compiler was released 8-Jun-2012, maintenance
ended 9-Jul-2019, and service ends 30-Apr-2020.)

This change fixes all observed atomic issues and unifies XL C/C++
with GCC/Clang.
