Added prebuilt Linux ARM64 binaries to CI

refs #1362

- the referenced PR added Linux ARM64 and ARMv7 prebuilds to CI so we can
  get prebuilt binaries upon releasing
- CI has recently been reworked so I've rebased the PR and fixed it up
- unfortunately, `node-pre-gyp` seems to ignore the difference between
  armv6 and armv7, and treats them both as `arm` so I've had to disable
  prebuilds for them for now
- building via QEMU is INCREDIBLY slow so I've configured
  it to only run during a release or upon manual execution
- full credit to @n1ru4l for the original PR

+Unfortunately, [node-pre-gyp](https://github.com/mapbox/node-pre-gyp) cannot differentiate between `armv6` and `armv7`, and instead uses `arm` as the `{arch}`. Until that is fixed, you will still need to install `sqlite3` from [source](#source-install).
+
 Support for other platforms and architectures may be added in the future if CI supports building on them.
 
 If your environment isn't supported, it'll use `node-gyp` to build SQLite but you will need to install a C++ compiler and linker.
 
 ### Other ways to install
 
-It is also possible to make your own build of `sqlite3` from its source instead of its npm package ([See below.](#building-from-the-source)).

 The `sqlite3` module also works with [node-webkit](https://github.com/rogerwang/node-webkit) if node-webkit contains a supported version of Node.js engine. [(See below.)](#building-for-node-webkit)
