Enable streaming serializer for everybody by default

Praefect functions as a proxy, but there are a few RPCs that are only in
praefect and do not get proxied to gitaly. To test functionality that
hits these RPCs, we need a way to hit a praefect instance that talks to
a gitaly instance.

This MR sets up praefect in front of the existing gitaly that is used in
tests.

Update ruby-prof to 1.3.1

Closes #204771

See merge request gitlab-org/gitlab!28019

This removes the feature flag for broadcast placeholders and only
enables placeholders for notifications. This feature flag changes
the logic intentionally. During initial development it came
apparent that placeholders only make sense for notifications, but
this was then not reflected in the final MR.

This MR fixes this, removes the feature flag, adds a test for the
new code path and cleans up the specs.

https://gitlab.com/gitlab-org/security/gitlab-workhorse/-/merge_requests/3
changed Workhorse so that it always provided `file.path` when
`direct_upload` was enabled, even if that path was blank.

Whereas we were checking for `path` not being `nil`, we now need to
check that it's present.

**Why?**
- This is no longer needed and was replaced by
  helpers/jquery
- We should just use the __mocks__ folder for any
  mocking of node_modules
- This will improve performance slightly since we
  won't be manually reading this from the file
  system every time

This replaces underscore for lodash inside the
EE folder for:
* protected_tags
* protected_branches
* protected_environments
