CI: Split the Build Jobs for Arm64 and x86_64

[lupyuen]

Summary

This PR creates the new CI Build Jobs arm64-01 and x86_64-01. The new jobs will split and offload the Arm64 and x86_64 Build Targets from other. This will reduce our usage of GitHub Runners, to comply with the ASF Policy for GitHub Actions. (Recently we see more PRs for Arm64 and x86_64)

Before the Split: Simple PRs (One Arch and/or One Board) for Arm64 and x86_64 require almost 1 hour for CI Build

• other (57 mins): AVR, SPARC, x86, PinePhone, QEMU Arm64, QEMU x86_64

After the Split: Simple PRs for Arm64 and x86_64 will complete under 30 mins

• other (24 mins): AVR, SPARC, x86
• arm64-01 (29 mins): PinePhone, QEMU Arm64
• x86_64-01 (9 mins): QEMU x86_64

To skip more unnecessary builds: Our Build Rules arch.yml shall ignore the label "Area: Documentation", so that a Simple PR + Docs is still a Simple PR. Previously we experienced longer CI Build Times, just because we added docs to our Simple PR. (Now our PR shall be built exactly like a Simple PR)

This update will help us comply with the ASF Policy for GitHub Actions, since we need to drastically reduce our usage of GitHub Runners: #14376. The updated CI code is explained here: #13775

Impact

With this PR, Build Jobs for Arm64 / x86_64 / Other will finish earlier:

• Before the Split: Arm64 and x86_64 Build Jobs take up to 57 mins (other) to complete.

• After the Split: Arm64 and x86_64 Build Jobs will take at most 29 mins (arm64-01) to complete.

• Simple PRs labeled "Arch: arm64" and/or "Board: arm64" will now build arm64-01. (Instead of other)

• Simple PRs labeled "Arch: x86_64" and/or "Board: x86_64" will now build x86_64-01. (Instead of other)

• Simple PRs with Docs will also build faster. (Simple PRs are limited to only One Arch and/or One Board)

The Updated CI Workflow shall be synced to nuttx-apps repo in the next PR.

Simple PR for Arm64 / x86_64: We tested by creating Simple PRs for Arm64 and x86_64

• "Arch: arm64" will build only arm64-01
• "Board: arm64" will build only arm64-01
• "Arch: arm64, Board: arm64" will build only arm64-01
• "Arch: x86_64" will build only x86_64-01
• "Board: x86_64" will build only x86_64-01
• "Arch: x86_64, Board: x86_64" will build only x86_64-01

Simple PR with Documentation: We tested by creating Simple PRs that have docs

• "Arch: arm, Area: Documentation" will build only arm-01 to arm-14
• "Board: arm, Area: Documentation" will build only arm-01 to arm-14
• "Arch: arm, Board: arm, Area: Documentation" will build only arm-01 to arm-14

Regression Test: We tested by creating Simple PRs and Non-Simple PRs

• "Arch: arm" will build only arm-01 to arm-14
• "Board: arm" will build only arm-01 to arm-14
• "Arch: arm, Board: arm" will build only arm-01 to arm-14
• "Arch: risc-v" will build only risc-v-01 to risc-v-06
• "Arch: sim" will build only sim-01 to sim-02
• "Arch: xtensa" will build only xtensa-01 to xtensa-02
• Merging a PR will also build All Targets
