Implement GetWavePosition API for both Legacy and MMixer modes.
[WDMAUD.DRV]
- Fix wrong I/O control code passed to DeviceIoControl for Legacy mode. Use IOCTL_GETPOS instead of IOCTL_OPEN_WDMAUD, to use the correct routine.
- Implement WdmAudGetWavePosition for MMixer mode, as it was completely unimplemented there. Call an appropiate MMixer routine and return back resulting wave position.
[WDMAUD]
- Implement WdmAudGetPostion routine, which is used by Legacy mode, and call the same MMixer routine from it too.
- Handle it in IOCTL_GETPOS I/O control request of dispatch routine.
[MMIXER]
- Implement MMixerGetWavePosition internal routine, which is called by both Legacy and MMixer modes, and does the actual work of retrieving playback position.
- Call an apporpriate KSPROPERTY_AUDIO_POSITION property from it, and return in the output resulting KSAUDIO_POSITION.PlayOffset member, which contains the current playback position offset, to be returned to the caller.
This fixes a failure retreiving the current audio playback position snd subsequent playing the audio data by several 3rd-party applications which are using this API (for example, some Gecko based browsers by @roytam1: Basilisk (Serpent) 52.9.0 IA-32 build, NewMoon 28.10.7 IA-32 build and KMeleon 76.5.3 Goanna engine).
CORE-19542
Calculate size of the additinal data based on the format tag specified by the caller.
For PCM wave format, it should be zero, and for all others,
it should be taken from cbSize member of WAVEFORMATEX structure.
- Initialize data size for each format appropriately.
- Append it to the total pin connect allocation size, to allocate enough memory for it.
- Use it as additional data size for requested wave format.
- Append it to the total size of data format.
- Add SAL2 annotations for MMixerInitializeDataFormat function.
Fixes two crashes in winmm:capture and winmm:wave winetests, which have been introduced by 12b3272d9e.
So this is an addendum to that commit.

[MMIXER] Implement hadling WAVE_FORMAT_EXTENSIBLE audio format
Fix opening audio device error when trying to open it with WAVE_FORMAT_EXTENSIBLE format tag set in wFormatTag member of WAVEFORMATEX:
- Pass additional data size from WAVEFORMATEX.cbSize to pin data format.
- Append it to the whole size of pin data format (KSDATAFORMAT.FormatSize).
- Set additional fields in WAVEFORMATEXTENSIBLE structure (data format, BPS and channel mask) when WAVE_FORMAT_EXTENSIBLE is used. They are used by our inbuilt Intel AC97 miniport driver at least. It simply fails when these members are not set.
- Fix pin connect allocation size by appending an additional data size from WAVEFORMATEX.cbSize to KSPIN_CONNECT + KSDATAFORMAT + WAVEFORMATEX. This allows to proerly initialize additional extensible data and avoids kernel memory leakage when using extensible audio format.
- Remove format tag check which allowed WAVE_FORMAT_PCM to be opened correctly. So now all possible audio formats can be opened properly at least (although it does not mean they may work correctly).
This fixes the audio playback for all apps those are supporting extensible audio data and use it by default (e. g. AIMP 5.30, QMMP 0.12.17, all Chrome/Chromium-based browsers, GameDev Tycoon Demo game etc.).

* [KS] Allow passing additional extensible audio data when extensible audio format is used
- Append additional data size from WAVEFORMATEX.cbSize to pin connect size passed to KsCreatePin. If the tag is WAVE_FORMAT_PCM, then this member should always be zero. So in that case, no any additional data is passed to creation request, and the passed data size is correct for PCM too (KSDATAFORMAT + WAVEFORMATEX).
This fixes audio playback in several apps those are supporting extensibble audio and use it by default (e. g. AIMP 5.30, QMMP 0.12.17, all Chrome/Chromium based browsers, GameDev Tycoon Demo game etc.).

* [WDMAUD.DRV] Pass the correct additional data size to I/O control request
Store a correct size of additional data in WAVEFORMATEX.cbSize when performing open of audio device, when WAVE_FORMAT_EXTENSIBLE audio format is used.
It allows to properly open audio device with Legacy APIs enabled too.
This fixes audio playback in several apps those are using extensible audio data (e. g. AIMP 5.30, QMMP 0.12.17, all Chrome/Chromium based browsers, GameDevTycoon Demo game etc.).

Serge plans a follow up that will remove all other remaining YDEBUG in the source tree.
The ones covered here he considered to be the most trivial ones.
