This PR proposes to enhance the CI Workflow, to skip the unnecessary NuttX Builds. Currently, NuttX Devs wait for the CI Builds to complete across All Architectures (Arm32, Arm64, RISC-V, Xtensa), even though they modified a Single Architecture. With this PR, the CI Workflow will build only the Modified Architecture.
The solution uses the Arch Labels for PRs. We target only the Simple PRs: One Arch Label + One Size Label (e.g. "Arch: risc-v, Size: XS")
- If "Arch: arm / arm64" is the only non-size label, then we build `other`, `arm-01`, `arm-02`, ...
- If "Arch: risc-v" is the only non-size label, then build `risc-v-01`, `risc-v-02`
- If "Arch: xtensa" is the only non-size label, then build `xtensa-01`, `xtensa-02`
- The above rules apply when the PR is Created or Modified
- When the PR is Merged: All targets shall be built
