[WDMAUD.DRV] Revert "Workaround multiple issues with AC97 driver from rapps"

This reverts commit 0.4.15-dev-791-g
    6d7ebc20481a587bd19e8a8049317113071b0817

It was a workaround just. To bypass sysaudio. It had a very positive effect on
    our playback performance, but using the different codepaths did also lead to
    regressions, that I have no idea how to address, therefore I think it's my
    personal responsibility to revert it. I guess it's better to improve on the
    code-paths that we intend to use finally, instead of fixing what will
    be dead paths in the future.

The revert will fix:
    - CORE-17277 crash of dsound:duplex on "GCCLin_x86 on Test VBox"
    - CORE-17278 crash of dsound:capture on "GCCLin_x86 on Test VBox"
    - CORE-17285 Realtek HD Audio does no longer work in ReactOS

But ofc now we will suffer again from very severe things that the hack could workaround:
    - CORE-13202 Unhandled exception from wdmaud.drv when recording sound in Scratch 1.4 leads to app-crash
    - CORE-13488 A deadlock in "DiabloII" character selection screen and "The Lion King II"
    - CORE-8726/CORE-9986/CORE-16564 AC97 driver from rapps will need reboot-orgies again, does not longer
      work in the same session that we installed the driver
    - CORE-9981 "DosBox + Commander Keen6" totally garbled sound output instead of music
        "ScummVM 2.0 with Monkey Island 2" totally garbled sound output instead of music
    - the test execution times of "GCCLin_x86 on Test VBox" will almost double
