Construct NeighborCell from CellInfo

This change will map calls to getNeighboringCellInfo() to
calls to getAllCellInfo() so that the underlying support
for this API can be removed, and it will only return the
information from getAllCellInfo() which is available to
callers of getNeighboringCellInfo().

Bug: 62490173
Test: tested manually using SL4A with both O-MR1 and current
    target SDKs
