Tools: Topology: Build topologies with 2-way speaker crossover

This patch modifies cavs-sdw.conf to use sdw-amp-xover.conf
when crossover feature is enabled with SDW_AMP_XOVER set
to true.

The built SDCA function topologies are
sof-sdca-2amp-id2-xover.tplg and
sof-sdca-2amp-feedback-id3-xover.tplg.

The currently built topology duplicates a stereo L,R stream
into L,R,L,R stream and applies 4th order Linkwitz-Riley
low-pass for the first pair and high-pass for the second pair.

The crossover frequency is set to 2 kHz as example. The
crossover parameters should be changed to match the acoustical
design of speaker acoustics of the device. Also there could be
different channels mappings and high/low-pass apply need.

Other variants can be created with the Octave scripts in the
next patch.
