[PATCH v10 0/2] MR10906: sapi: Implement ISpVoice::SetPriority and GetPriority.

[Bohdan Tkachenko (＠BohdanTkachenko)]

sapi: Implement ISpVoice::SetPriority and GetPriority.

Previously both methods returned E_NOTIMPL. Store the priority on the speech_voice struct and validate the value against SPVPRI_NORMAL,\
SPVPRI_ALERT and SPVPRI_OVER.

This unblocks Overwatch 2's Audio Captions accessibility TTS, which calls\
SetPriority during voice setup and aborts on any non-S_OK result.

Add tests covering priority round-trips between SPVPRI_NORMAL, SPVPRI_ALERT and SPVPRI_OVER, and verify the default is SPVPRI_NORMAL.
