Subject: [PATCH] ci: add build-one workflow for single-platform test builds
 (#88)

The Build workflow's matrix-of-everything makes it slow and noisy to
test a single device profile. Mirrors the build-one workflow already
present in OpenIPC/firmware.

Takes a full platform name (e.g. hi3518ev200_lite_switcam-hs303-v2)
and runs only that build via builder.sh.
