Go Module Proxy MVC

Closes #27376

See merge request gitlab-org/gitlab!27746

- Various fixes and improvements
- Hide proxy behind a feature flag, due to performance issues: #218083
- Add a feature flag for testing to disable strict go.mod validation
- Document why case en/decoding is necessary
- Refactor pseudo-version processing
  - Move logic from VersionFinder to ModuleHelpers
  - Document reasoning for matching and validation
- Replace BasicAuthHelper and custom method with route setting
- Use serach_files_by_name instead of tree to improve performance
- Use correct content type for zip: closes #214876

- Reduce coupling between GoModule and VersionFinder
- Do not fetch go.mod when blobs have already been fetched

- Various fixes and tweaks
- Improve checksum database documentation

- Resolve discussions on !27746
- Document fetching private packages via `.netrc`
- Include required scope for API token

- Clean up pseudo-version logic
- Batch and memoize fetching blobs for a version
  + Fixes Gitaly N+1
- Remove archive generation from GoProxy (into GoModuleVersion)
- Test module finder for path traversal
- Also, add GitLab version to GoProxy API details

See !27746

- Fix rubocop disable comments
- Move `before` block to before tests
- Correct rubocop alerts due to new rules
- Use shared examples to clarify Go proxy spec
- Enable HTTP Basic authentication for Go proxy
  + Support both HTTP basic and normal token header/query var
  + Remove custom `find_project!` helper and use basic auth helpers
- Validate GoModuleVersion type attribute
- Implement testing factories
- Implement specs for untested new classes
- Add a Settings helper for Go URLs

- Allow CI job tokens
- Return 401 when project is not public and request is not authenticated
- Add assertions to spec to verify authn/authz

- Fix zip entry paths. The Go proxy spec requires zip entries to conform
  to `module@version/file`, where `file` is the path within the module.
- Fix /v2+ handling. For major versions 2+, the module name must include
  the major version as a suffix, e.g. /v2.
- Handle case encoding. Requests to the Go proxy encode uppercase
  characters in URLs as '!' followed by the character in lowercase.
- Per Zoom discussion with @trizzi, @sabrams, and team, modules with an
  invalid module name in go.mod will be ignored, initially.

- Call package authorization helpers
- Add change long entry
- Fix rubocop violations
- Add basic documentation

Implement models, entities, presenters
