Sync GitLab linked issue back to Sentry on SentryIssue creation

See merge request gitlab-org/gitlab!23007

When importing, we want to create `refs/heads/:source_branch` in the
repository for each MR. Since the imported project already contains
the SHA, there's no need to use `fetch_source_branch` - we can just
create the ref directly.

Closes #196179

Creates a standalone vulnerability page

See merge request gitlab-org/gitlab!20734

- Adds in the standalone vulnerabilty page

- Renders a 404 on the vulnerability page if the
`first_class_vulnerabilities` feature flag is not present.
- Updates all the path helpers and related tests
- Adds tests for the new route

When a directory contains many submodules, we make a number of Gitaly
N+1 queries:

1. One TreeEntry RPC to look up each submodule
2. One TreeEntry RPC to read the `.gitmodules` file

The first item is redundant because we've already determined the tree
commit is a submodule. We can eliminate this query by skipping it
altogether.

The second item can be optimized by caching the contents of
`.gitmodules` once per directory. We already have a mechanism for
caching this in `SubmoduleLinks`. Now we just need to use it.

This significantly reduces Gitaly RPCs and closes two issues
with one stone:

1. https://gitlab.com/gitlab-org/gitlab/issues/35333
2. https://gitlab.com/gitlab-org/gitlab/issues/194380
