Remove obsolete `kInterpreterAbi`.

It was no longer used (although still handled in `CreateTrampoline`).

Bug: 283082089

Test: m test-art-host-gtest
Test: run ART test 001-HelloWorld on a Linux RISC-V VM:
  lunch aosp_riscv64-userdebug

  export ART_TEST_SSH_USER=ubuntu
  export ART_TEST_SSH_HOST=localhost
  export ART_TEST_SSH_PORT=10001
  export ART_TEST_ON_VM=true

  . art/tools/buildbot-utils.sh
  art/tools/buildbot-build.sh --target

  # Create, boot and configure the VM.
  art/tools/buildbot-vm.sh create
  art/tools/buildbot-vm.sh boot
  art/tools/buildbot-vm.sh setup-ssh  # password: 'ubuntu'

  art/tools/buildbot-cleanup-device.sh
  art/tools/buildbot-setup-device.sh
  art/tools/buildbot-sync.sh

  art/test.py --target -r --prebuild --no-prebuild --ndebug --no-image \
    --64 --interpreter 001-HelloWorld
