1. It's huge.
2. It's loaded on page load, which makes the page take 13 seconds.
3. It has a terrible UX.

Closes #28992

Closes #29531

Reuse same search form and behavior for dashboard#projects, group#projects
and admin#projects. Repsect all other options like sorting, personal
filter when search projects by name. Create FilterableList JS class to
handle identical behaviour of projects and groups lists.

This change also makes filtering and sorting availabe on explore#projects
and explore#groups no matter if you are logged in or not.

Altered specs that click capitalised New Snippet button

Applied review feedback missed in  Changes `.no-comment` `opactiy: 0.5` to `opacity: .5`

Added `.btn-wide-on-xs` and applied to snippet buttons

No longer shows New Snippet button to users who aren't able to create a new snippet in the given context.

Also removes the plus icon from the New Snippet buttons, as they're no longer used in other creation buttons.

Fixes #14595.

1. Fix double bottom border if pagination

projects list with seach nad pagination and render html form with
project-filter-form id and text field with filter_projects name.
