Remove isValidBelForCell
This Arch API dates from when we were first working out how to implement placement validity checking, and in practice is little used by the core parts of placer1/HeAP and the Arch implementation involves a lot of duplication with isBelLocationValid. In the short term; placement validity checking is better served by the combination of checkBelAvail and isValidBelForCellType before placement; followed by isBelLocationValid after placement (potentially after moving/swapping multiple cells). Longer term, removing this API makes things a bit cleaner for a new validity checking API. Signed-off-by: gatecat <gatecat@ds0.me>
