Subject: [PATCH] CI: Validate all defconfig files before running any builds

Currently, CI Build Jobs will validate the `defconfig` file just before compiling the NuttX Target (like `rv-virt:nsh`). This means that the Build Job might run for a while, before hitting a `defconfig` error and failing much later.

This PR updates the CI Workflow `build.yml` to validate all `defconfig` files before running any builds. This means that errors in the `defconfig` files will be flagged earlier. And the Build Job will terminate (with an error) before any build begins.

This behaviour is helpful for resolving CI Build Issues quickly. The code is derived from `tools/testbuild.sh`. The enhancement was suggested here: https://github.com/apache/nuttx/issues/14259
