Merge bitcoin#17549: ci: misc cleanups

fad88e6 ci: Remove use of cd (MarcoFalke)
fa2941b ci: Remove unmaintained extended_lint (MarcoFalke)
fa04187 scripted-diff: Use ci DEPENDS_DIR, remove BASE_BUILD_DIR (MarcoFalke)
fa0656d ci: Add DEPENDS_DIR variable, Add documentation for folders (MarcoFalke)
faeeca8 scripted-diff: Move various folders to ci scratch dir (MarcoFalke)

Pull request description:

  Some minor cleanups:

  * Remove unused and unmaintained extended_lint to avoid ci bottlenecks and waste of CPU
  * Move all folders that hold temporary ci files to the ci scratch dir (except for the build dirs)
  * Add some documentation to folders and remove the `BASE_BUILD_DIR` alias for the root directory
  * Fixes bitcoin#17178 by removing `cd`
