- Adds a negatable have_text/have_content matcher to be used instead
  of Capybara's built-in ones
- Include all custom matchers during RSpec config. This should make it
  simpler to add more matchers - we just need to put them in
  qa/spec/support/matchers in the Matchers module
- Update a few tests that used `expect(page).to have_content`

Block LFS requests on snippets

See merge request gitlab-org/gitlab!45874

The repository routes for project repositories are ambiguous and also
match project snippet repositories, so LFS requests for project snippets
will work but snippets are not ready yet to properly support LFS.

We can work around this by checking `#lfs_enabled?` on the `container`
instead of the `project`, which for snippets will be the snippet itself,
and `Snippet#lfs_enabled?` is currently hard-coded to return `false`.

To simplify things, we also remove the project-specific access check and
use `lfs_download_access?` instead to determine wether to expose the
existence of the project (404 response) or not (403 response), when
sending an error response. When LFS is disabled on the container we now
also send a 404 instead of a 403.

[GraphQL] Error tracking: use Global-ID scalar

See merge request gitlab-org/gitlab!36098

This changes the type of id from ID to the more meaningful
GlobalIDType[Gitlab::ErrorTracking::DetailedError]

This is a bit of an interim fix, since these IDs (being sentry IDs
really) don't make much sense as global IDs, which are meant to
represent application resources.
