7142db28a8 HeAP: Make HeAP placer optional 
A CMake option 'BUILD_HEAP' (default on) configures building of the
HeAP placer and the associated Eigen3 dependency.

Default for the iCE40 is SA placer, with --heap-placer to use HeAP

Default for the ECP5 is HeAP placer, as SA placer can take 1hr+ for
large ECP5 designs and HeAP tends to give better QoR. --sa-placer can
be used to use SA instead, and auto-fallback to SA if HeAP not built.

1b28bdd121 ecp5: cmake: Search for pytrellis.so in multiple locations 
If a distro-specific "trellis-devel" package is used, the
pytrellis.so library might be located in a dedicated directory,
rather than under TRELLIS_ROOT.

Search for pytrellis.so in a list of directories, then subsequently
use the first match as part of PYTHONPATH.
