[tests-only] [full-ci] Do not do earlyFail in CI if full-ci requested

[phil-davis]

Description

With this PR, a developer can mention full-ci in the PR title, and that will override the earlyFail behavior.

Normally when the first UI test pipeline fails, it cancels the whole build, to save CI resources.

But now, if you mention full-ci in the PR title, then the UI tests pipelines will all run to completion, even if one or more of them fails. That can help a developer to see all the fails "at once". And they can do it without actually editing .drone.star - so the PR can be merged when it passes (there will be no need to revert an edit of .drone.star)

Looks good - the UI test pipeline does not have the earlyFail steps like stopBuild
