Richard Antalik b21695a507 VSE: Add sound strip retiming support
This patch contains changes needed for retiming sound strips.

`BKE_sound_set_scene_sound_pitch()` is replaced by
`BKE_sound_set_scene_sound_pitch_constant_range()` which uses new
Audaspace interface to set pitch in bulk.
This is done in `SEQ_retiming_sound_animation_data_set()` where retimed
sections are created for each strip. When strip is inside of meta
strip(s), the retimed sections of meta and actual strip are split where
they intersect and pitch is multiplied where they overlap. Each section
will have pitch value that is provided to audaspace.

Waveform overlay now represents retimed audio accurately.

Ref: #100337
