Merge bitcoin/bitcoin#30877: code style: update .editorconfig file

95560616fb code style: update .editorconfig file (Sebastian Falbesoner)

Pull request description:

  Updates the .editorconfig file, first introduced in 2021 (see PR #21123, commit 7a135d57) w.r.t. following changes:
  - consider Rust .rs files (relevant since #28076, commit bbbbdb0c)
  - reflect build system change to CMake (#30454, #30664)
  - add setting for bare Makefile still used for depends builds

  Can be tested e.g. by using the editorconfig-vim plugin (https://github.com/editorconfig/editorconfig-vim). The PR is made under the assumption that the file is still considered useful, especially for new contributors. If people feel like that's not the case anymore, the alternative is to delete it, obviously.

Top commit has no ACKs.
