repl: FormatValue factor out printing of null values

Browse source 
This value was too long for our function length lint rule, and factoring
out the printing of null values makes this more balanced with how we're
already handling unknown values and sensitive values so that the main
body of FormatValue is focused on the normal value printing case.
