Revert "edtlib: test filters set by including bindings"

This unit test was added specifically to cover a regression
reported by the CI while working on [1].

Further work on related issues [2] showed that:
- [1] and [2] are dead end: we need to first rethink
  how bindings (and especially child-bindings) are initialized
- the inclusion mechanism supported by Zephyr deserves more systematic
  testing in edtlib if we want to work with confidence

The approach we choose is to:
- revert all changes made in [1]
- from there, systematically add unit tests as we address
  the issues we identified (or the additional features we need)
  one after the other

[1] edtlib: fix last modified semantic in included property specs
[2] edtlib: Preserve paths of properties from included child bindings

This reverts commit 33bb3b6.
