ASoC: SOF: ipc4-topology: Replace fake flexible arrays with flexible-array member
Zero-length arrays as fake flexible arrays are deprecated and we are
moving towards adopting C99 flexible-array members, instead.

Use the DECLARE_FLEX_ARRAY() helper macro to transform zero-length
arrays in unions with flexible-array members.

Address the following warnings found with GCC-13 and
-fstrict-flex-arrays=3 enabled:
sound/soc/sof/ipc4-control.c:176:77: warning: array subscript i is outside array bounds of ‘struct sof_ipc4_ctrl_value_chan[0]’ [-Warray-bounds=]

sound/soc/sof/ipc4-topology.c:1476:36: warning: array subscript i is outside array bounds of ‘struct sof_ipc4_ctrl_value_chan[0]’ [-Warray-bounds=]

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].
