Clicking search pill focuses field

When clicking the pill in the search field, it now focus the field. Previously you would have to make sure you click in the field.

Fixed an issue where clicking out of the field wouldn't remove the focus
outline

Also reduced some of the HTML to remove what isn't needed

Fix serious performance bug with rendering Markdown with InlineDiffFilter

Nokogiri's `node.replace` was being unnecessarily called for every text node in
the document due to a comparison bug. The code previously was comparing the
HTML representation of the full document against the text node, which would
always fail. Fix the comparison to just compare the modified text.

Closes #18011

Fix link to blank group icon

When the group is the default blank icon, this needs to use the
`image_path` helper; otherwise, the link won't work if assets are
precompiled. This still works fine for uploaded icons in either case.

Closes #14446.

Minor doc updates

## What does this MR do?

Adds to and clarifies some documentation. Specifically, when using `gdb` to debug you need to detach and exit when done. Next, this clarifies the type of file locking that we require.

Thanks to @northrup for the details about mandatory vs. advisory file locking.

Note: These were two really small changes so I combined in to one merge request. However, I left the commits separate for clarity.

Load d3 only when necessary

Now d3 is only loaded on the users' show page and the graphs pages, where it's necessary.

Redo of !3993.

This decreases page size from 4.6MB to 4.3MB for a given Activity page (before compression), or a savings of 300KB. This is essentially a proof of concept for removing larger dependencies such as the Ace Editor, Chart.js, and Raphael, which will likely provide another 1MB of savings on most pages (again, before compression).

Upgrade devise, devise-two-factor, and attr_encrypted

Devise 4 includes support for Rails 5, working towards #14286. devise-async doesn't support Devise 4.0 and in 4.1 the bug that was blocking using Devise's built-in ActiveJob integration was fixed. So devise-async is removed. devise-two-factor 3.0.0 is required for Devise 4 support.

attr_encrypted and encryptor are optional but recommended upgrades for devise-two-factor 3.0.0. The mode and algorithm will need to be changed in order to update to attr_encrypted 4.x in the future.
