Performance improvement on Projects::BuildsController#show.html

What does this MR do?

This is performance improvement on Project::BuildsController#show.html by removing unused code.

Are there points in the code the reviewer needs to double check?

log_state (data-log-state) shouldn't be provided in HTML view as it is only required in the JSON response.

Why was this MR needed?

This skipping to call Ansi2html can resolve the GitLab instance being in stuck when a user opens a build page which has a larger (100kB, 1MB or more) trace as Ansi2html is slow (#27724 (closed)).
