Revert "[Backport release-24.11] nixos/alsa: rebirth from the ashes"

[Ma27]

Reverts #371385

Rationales for revert:

• First of all, this is a breaking change as outlined by @fpletz: nixos/alsa: rebirth from the ashes #337345 (comment). To quote our contribution guidelines:

  The release branches should generally only receive backwards-compatible changes, both for the Nix expressions and derivations

  I don't see a missed deadline (no matter who's at fault) as sufficiently pressing reason to overrule this.

• Second, nobody reads the 24.11 release notes after having upgraded to 24.11, so this is pretty questionable.

Whether or not to revert on master is still to be discussed as brought up in #337345. At least the 24.11 release notes require a fix-up.

Agreed. The module can be eventually reintroduced without breaking changes.

[Ma27]

Given two approvals including from the original author I'll merge now.

The release notes also require adjustment on master, i.e. to have correct instructions in 25.05. Do you plan to take care of this @rnhmjoj?

I guess you can revert the PR on master for now: I'll make a new one with release notes for 25.05.
I'm thinking about leaving hardware.alsa.enablePersistence and starting a new ALSA module under a different namespace, like programs.alsa.
