This change enabled the use of low-latency shared mode if the desired
sample rate matches the native sample rate.

AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM is incompatible in exclusive mode
and low-latency shared mode.

This only applies when the playback sample format is configured as
ma_format_f32. Clipping is enabled by default and can be disabled by
setting ma_device_config.noClip to true.

This commit makes it well defined as to whether or not the output
buffer passed in to the data callback is initialized to zero or left
undefined. By default it's initialized to zero, but can be changed to
undefined by setting noPreZeroedOutputBuffer in the device config.
