NSKeyedUnarchiver methods should take Data
NSKeyedUnarchiver methods should take Data

We missed a few NSKeyedUnarchiver methods during our original renaming
for Swift — some of these methods still take NSData when they can take
Data. We can add Data variants which bridge to NSData to fix this in a
backwards-compatible way.
