CI: Split the Build Jobs for Arm64 and x86_64

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)

The updated CI code is explained here: https://github.com/apache/nuttx/issues/13775
