Merge bitcoin/bitcoin#33514: ci: clear out space on CentOS, depends, gui GHA job

e07e57368e ci: clear out space on centos job (will)

Pull request description:

  Fixes #33293

  Clear out space on jobs running on GHA by deleteing unnecessary files.

  Raised in #33293 which pointed to a solution like b7f04d7822 which is adapted slightly here.

  Only runs when cache provider (runner) is `gha`.

  A run on my fork can be seen here: https://github.com/willcl-ark/bitcoin/actions/runs/19703413734/job/56444984809
