Integrates the new features of the the Kokoro PSM Interop install library introduced in grpc/psm-interop#73. Nearly all common functionality was moved from per-language/per-branch PSM Interop build scripts to [psm_interop_kokoro_lib.sh](https://github.com/grpc/psm-interop/blob/main/.kokoro/psm_interop_kokoro_lib.sh): 1. The list of tests in the each test suite 2. Per-test-suite flag customization 3. `run_test` methods 4. `build_docker_images_if_needed` methods 5. Generic `build_test_app_docker_images` methods (simple docker build + docker push + docker tag). grpc-java is one exception, as it doesn't run docker directly, but a cloudbuild flow. Now all PSM Interop jobs share the same buildscripts by all test suites: 1. buildscript that invokes the test: `psm-interop-test-{language}.sh` (configured as `build_file` in the build cfg) 2. buildscript that builds the xDS test client/server and publishes them as a Docker image: `psm-interop-build-{language}.sh` (conventional name called from `psm_interop_kokoro_lib.sh`) `psm-interop-test-{language}.sh`: 1. Sets `GRPC_LANGUAGE`, `BUILD_SCRIPT_DIR` environment variables. 2. Downloads the shared `psm_interop_kokoro_lib.sh` from the main branch of the psm-interop repo. 3. Sources `psm-interop-build-{language}.sh` 4. Calls `psm::run "${PSM_TEST_SUITE}"` (`PSM_TEST_SUITE` configured in the cfg file). `psm-interop-build-{language}.sh`: 1. Defines `psm::lang::build_docker_images` which is called from `psm_interop_kokoro_lib.sh`. 2. Invokes any repo-specific logic. 3. May use `psm::build::docker_images_generic` for generic Docker build, tag, push, or provide implement its own build/publish method.
