feat!: bump LLVM minimal version to 8

  * Disable nightly builds until we fix setup-node to support mirrors
    again
  * Add matrix of Ubuntu versions (18.04, 20.04)
  * Add matrix of llvm versions (8, 9)
    * Versions before 8 don't pass frame-test tests

Because we're bumping llvm/lldb versions in CI, we're technically
bumping the minimal LLVM version users needs to have installed.
Therefore, this is a breaking change.
