Switch workflows to new EKS runners

[demisx]

The new runners have been successfully tested with Verify PR workflow. We need to initiate the switch.

Tasks:

• Switch jobs in "Verify PR" workflow switch Verify PR workflow to EKS runners #1363
• (devOps) Resolve Process completed with exit code 255
• 4/17+: Switch remaining jobs in "Verify PR" workflow (except failing code coverage)
• Switch "Merge PR" workflow switch Merge PR workflow to EKS runners #1459
• Switch "Release" workflow switch Release workflow to eks runners #1460
• Use ci-base-image globally
• Add v1 label to the legacy runners update runner labels #1636
• Rename testing, v2 -> build, v2 label update runner labels #1636
• Ask devOps to disable legacy runners Still needed for couple of jobs

Blocked by:

• Upgrade Rust #1449

While testing release workflow on the new EKS runners, I’ve run into this error in “Build Deterministic WASM” job that also exists on main and will pop-up next time someone cuts a release:

error: failed to run custom build command for `polkadot-runtime v0.9.36 (https://github.com/paritytech/polkadot?branch=release-v0.9.36#dc25abc7)`

Caused by:
  process didn't exit successfully: `/build/runtime/frequency/target/srtool/production/build/polkadot-runtime-f8cb2ea1fb20adc3/build-script-build` (exit status: 1)
  --- stderr
  Rust nightly not installed, please install it!

The failed job is “Build Deterministic WASM” : https://github.com/LibertyDSNP/frequency/actions/runs/4853427916/jobs/8650492538

We need #1449 to be resolved first. Also, per @saraswatpuneet and @wilwade, upgrading the polkadot version should include updating rust and toolchain if needed.

Another error that may be resolved by #1449:

The “Install Subwasm” step currently fails in CI Release workflow with this error:

= note: this error originates in the macro wasm_to_libcall_trampoline which comes from the expansion of the macro wasmtime_environ::foreach_builtin_function (in Nightly builds, run with -Z macro-backtrace for more info)
