use NSW as a precision layer in MuonSelectionTool
as discussed on ATLASMCP-167, we introduce NSW as a precision layer into MuonSelectionTool. Since the new precision layer criterion on NSW is not yet implemented in reconstruction, this MR modifies the re-calculation of precision layers in MuonSelectionTool. So far the re-calculation is placed in the getQuality function. To harmonize the definition of precision layers among MuonSelectionTool, it's moved to the fillSummary. When RecalcPrecisionLayerswNSW=True, MuonSelectionTool re-calculates precision layers with NSW. Also when EndcapHighPt=True, the tool enables HighPt WP in endcap.
