Remove "Add Sbom Survey Banner"

What does this MR do and why?

Removes sbom survey banner.

Removal strategy

• Revert commit 3c70b090 from MR !76446 (merged) to reduce risk of missing something
• Manually and carefully resolve merge conflicts caused by a more recent refactor !77583 (diffs)
• Do not remove the re-usable ee/app/assets/javascripts/vue_shared/survey_banner/survey_banner.vue component so we can add banners easily in the future.
• Add changelog entry
• Manually test removal

And it's all about this Banner:

sbomBanner

It introduced a new vue_shared component survey_banner which was to be configured via props and would render a Banner like in the screenshot above.

Furthermore this new shared component is used to display the sbom Banner on the dependency list page, license compliance page, group and project security dashboards.

The Banner had a link, the ability to be dismissed (saved in LocalStorage) and the ability to be reminded in a given number of days.

It was behind the sbom_survey feature flag roll out issue: #348181 (closed)
