EMBA container build improvements for Emacs build testing.

* test/infra/gitlab-ci.yml: Moved from .gitlab-ci.yml. Use the
EMBA container registry with a different login token storage file
for each commit. Split test stages into prep, build, fast tests,
normal tests, platform tests, and slow (everything) and use
templates where possible.

* .gitlab-ci.yml: Include test/infra/gitlab-ci.yml and move all
content there.

.gitlab-ci.yml
