Remove deprecated scss files for audit controls
Problem
The audit controls have two files that can be removed once #223260 (closed) is completed and gitlab-ui!1748 (merged) is merged.
ee/app/assets/stylesheets/components/audit_logs/sorting_field.scssee/app/assets/stylesheets/components/audit_logs/date_range_field.scss
For sorting_field.scss the selector .gl-daterange-picker > div can be replaced with the class gl-lg-align-items-baseline.
