ASoC: SOF: ipc4-topology/pcm: Rename sof_ipc4_copier_is_single_format()

Rename the sof_ipc4_copier_is_single_format() to
sof_ipc4_copier_is_single_bitdepth() to clear the confusion of the use of
'format' when we are querying information on the bit depth.
Format is used to describe a combination of parameters (rate, channels,
sample format / bit depth).
Rename the flags used to store the result at the same time.
